[0002] The disclosure herein relates to an adhesive backing composition suitable for use in carpets and methods of using the same.BACKGROUND

[0003] Bitumen can be used in the production of carpets as an adhesive composition. In production, hot bitumen having a certain viscosity can be deposited onto a secondary backing layer. A conveyor belt carries the secondary backings layer with the deposited bitumen under a doctor blade, which allows for an even application of the bitumen to the secondary backing layer. Immediately after passing under the doctor blade, an additional layer of the final carpet structure can be pressed into the hot bitumen using one or two lamination rollers depending on processing need.

[0004] However, it can be difficult to recycle carpets containing bitumen. In addition, bitumen is not considered particularly environmentally friendly. Thus, there is a need for alternative adhesive backing compositions that behave similarly to bitumen in the process described above. Such adhesive backing compositions and related methods are disclosed herein.SUMMARY

Thus, the following description is again provided as illustrative of the principles of the present invention and not in limitation thereof.A. Definitions

[0016] In this specification and in the claims that follow, reference will be made to a number of terms, which shall be defined to have the following meanings:

[0017] Throughout the description and claims of this specification the word “comprise” and other forms of the word, such as “comprising” and “comprises,” means including but not limited to, and is not intended to exclude, for example, other additives, components, integers, or steps. Furthermore, it is to be understood that the terms comprise, comprising and comprises as they related to various aspects, elements and features of the disclosed invention also include the more limited aspects of “consisting essentially of’ and “consisting of.”

[0018] As used herein, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an “adhesive backing” includes aspects having two or more such adhesive backings unless the context clearly indicates otherwise.

[0019] Ranges can be expressed herein as from “about” one particular value, and / or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and / or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It should be further understood that the endpoints of eachof the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

[0020] As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

[0021] References in the specification and concluding claims to parts by weight of a particular element or component in a composition or article, denotes the weight relationship between the element or component and any other elements or components in the composition or article for which a part by weight is expressed. Thus, in a composition or a selected portion of a composition containing 2 parts by weight of component X and 5 parts by weight component Y, X and Y are present at a weight ratio of 2:5, and are present in such ratio regardless of whether additional components are contained in the composition.

[0022] A weight percent of a component, unless specifically stated to the contrary, is based on the total weight of the formulation or composition in which the component is included.

[0023] As used herein, and unless the context clearly indicates otherwise, the term “carpet” is used to generically include broadloom carpet, carpet tiles, area rugs, and artificial grass (or turf). To that end, the term “broadloom carpet” refers to a broadloom textile flooring product manufactured for and intended to be used in roll form. The term “carpet tile” refers to a modular floor covering, conventionally manufactured in 18” x 18,” 24” x 24” or 36” x 36” squares, but other sizes and shapes are also within the scope of the present invention. Any of these exemplary carpets can be woven, non-woven, tufted, or needle-punched.

[0024] As used herein, “carpet” includes, for example, broadloom carpet, carpet tiles and portions of a carpet.

[0025] As used herein, “primary backing” layer, "second" layer, and “middle” layer are merely identifiers used for convenience, and shall not be construed as limitation on individual layers, their relative positions, or the laminated structure, unless otherwise specified.

[0026] The viscosity of the adhesive backing composition was measured according to ASTM D3236-15 at 150 °C unless otherwise noted in the specification at an alternate temperature.

Aliphatic tackifier resin

[0105] In some aspects, the aliphatic tackifier resin is an aromatic modified aliphatic tackifier resin. For example, an aliphatic tackifier resin can be those commercially available under the trade name ESCOREZ™, which is produced by ExxonMobil Chemical Company. For example, the aliphatic tackifier resin can be ESCOREZ™ 1315. In another example the aliphatic tackifier resin can be ESCOREZ™ 5637.

[0106] The term "tackifier" is used herein to refer to an agent that allows the polymer of the composition to be more adhesive by improving wetting during the application. The aliphatic tackifier resin may be produced from petroleum-derived hydrocarbons and monomers of feedstock including tall oil and other polyterpene or resin sources. The aliphatic tackifier resin is added to give tack to the adhesive and also to modify viscosity. Tack is required in most adhesive formulations to allow for proper joining of materials prior to the adhesive backing compositions solidifying.

[0107] The resins described above may be produced by methods generally known in the art for the production of hydrocarbon resins. See for example, the Kirk-Othmer Encyclopedia of Chemical Technology, 4th ed., Vol. 13, pp. 717-744. A preferred method for production of the resins described above is by thermally or catalytically polymerizing petroleum fractions. These polymerizations may be batch, semi-batch or continuous. Petroleum fractions containing aliphatic Cs to Ce linear, branched, alicyclic monoolefins, diolefins, alicyclic Cio diolefins can be polymerized. The aliphatic olefins can comprise one or more natural or synthetic terpenes, preferably one or more of alpha-pinene, beta-pinene, delta-3 carene, dipentene, limonene or isoprene dimers. Cs-Cio aromatic olefinic streams containing styrene, vinyl toluenes, indene, methyl-indenes can also be polymerized as such or in mixture with the aliphatic streams.

[0108] Thermal polymerization is usually carried out at a temperature between 160 °C and 320 °C, e.g., at about 250 °C., for a period of 0.5 to 9 hours, typically 1.5 to 4 hours.

[0109] The polymeric resin so produced is dissolved in an inert, de-aromatized or non-de- aromatized hydrocarbon solvent such as Exxsol™ or Varsol™ or base White spirit in proportions varying from 10% to 60% and preferably in the region of 30% by weight polymer. Hydrogenation is then conducted in a fixed-bed, continuous reactor with the feed flow being either an upflow or downflow liquid phase or trickle bed operation.

[0110] Hydrogenation treating conditions generally include reactions ranging in temperature of from about 100 °C to about 350 °C, preferably ranging from about 150 °C to about 300 °C, more preferably ranging from about 160 °C to about 270 °C. The hydrogen pressure within the reactor should not exceed more than 2000 psi, preferably no more than 1500 psi, and most preferably no more than 1000 psi. The hydrogenation pressure is, however, a function of the hydrogen purity and the overall reaction pressure should be higher if the hydrogen contains impurities to give the desired hydrogen pressure. Typically the optimal pressure used is between about 750 psi and 1500 psi, preferably between about 800 psi and about 1000 psi. The hydrogento feed volume ratio to the reactor under standard conditions (25 °C, 1 atm pressure) typically can range from about 20 to about 200.

[0135] The carpet comprises a secondary backing layer having a first surface and a second surface, wherein the first surface of the secondary backing is adhered to the back surface of the primary backing component by the adhesive backing compositions. In one aspect the secondary backing layer can comprise a woven material. In another aspect, the secondary backing layer can comprise a tape-tape yarn, or a tape-spun yam. In certain aspects, the secondary backing layer can be a tape-tape yarn woven material. In one aspect, the secondary backing layer cancomprise a polyolefin.

[0138] In yet other aspects, the secondary backing layer can comprise a non-woven material. In certain aspects, the secondary backing layer can comprise a spunbond non-woven material. The spunbond backing can be produced by depositing extruded, spun filaments onto a collecting belt in a uniform random manner followed by bonding the fibers. The fibers are separated during the web laying process by air jets or electrostatic charges. The collecting surface is usually perforated to prevent the air stream from deflecting and carrying the fibers in an uncontrolled manner. Bonding imparts strength and integrity to the web by applying heated rolls or hot needles to partially melt the polymer and fuse the fibers together. Since molecular orientation increases the melting point, fibers that are not highly drawn can be used as thermal binding fibers.
