Problems solved by technology

Another disadvantage of using the acrylic auxiliary resins and polymers disclosed in U.S. Patent No. 6,172,149 is that the latex-based inks and coatings made from these resins are less sensitive to commercially available and containing glycol ethers. Antibiotic resistance to commercial cleaners (such as FORMULA 409 available from Clorox) or alkaline chemicals is quite low

Embodiment 1

[0059] A carboxylic acid modified vinyl polymer composition is formulated in the following manner. A 500-ml round bottom flask equipped with a stirrer, heating mantle, reflux condenser, and addition funnel was charged with 109.1 g of EMPOL 1018 (a dimer acid available from Cognis) and 0.07 g of hypophosphorous acid. Heat the filling material to 175°C while stirring, and then start adding a composition consisting of 74.9g of styrene, 74.9g of α-methylstyrene, 92.4g of acrylic acid, and 3.76g of di-tert-butyl peroxide a mixture of monomers. The addition time of the monomer mixture was two hours, during which time the temperature of the batch was increased to 180°C. After completion of the addition of the monomers, stirring was continued for 1 hour at a temperature of 180°C. Next, another 0.39 g of di-tert-butyl peroxide was charged, and stirring was continued for another 2 hours to complete the polymerization reaction. When the reaction block was cooled, the obtained carboxy...

Embodiment 2

[0061] A carboxylic acid modified vinyl polymer composition is formulated in the following manner. A 500-ml round bottom flask equipped with a stirrer, heating mantle, reflux condenser, and addition funnel was filled with 71.6 g of EMPOL 1045 (a trimer acid available from Cognis), 37.5 g of SS turpentine ( a tall pitch pine resin available from MeadWestvaco), and 0.07 g of hypophosphorous acid. Heat the filling material to 175°C while stirring, and then start adding a composition consisting of 74.9g of styrene, 74.9g of α-methylstyrene, 92.4g of acrylic acid, and 3.76g of di-tert-butyl peroxide a mixture of monomers. The monomer mixture was added at a temperature of 175°C over a period of two hours. After the monomer addition was complete, stirring was continued for an additional hour while the temperature was increased to 210°C. Next, another 0.39 g of di-tert-butyl peroxide was charged, and stirring was continued for another 2 hours to complete the polymerization reaction...

Embodiment 3

[0063]A carboxylic acid modified vinyl polymer composition is formulated in the following manner. A 500-ml round bottom flask equipped with a stirrer, heating mantle, reflux condenser, and addition funnel was charged with 71.6 g of DIACID 1550 (a C-21 dicarboxylic acid available from MeadWestvaco), 37.5 g of SS turpentine (a tall oil pine resin available from MeadWestvaco), and 0.07 g of hypophosphorous acid. Heat the filling material to 175°C while stirring, and then start adding a composition consisting of 74.9g of styrene, 74.9g of α-methylstyrene, 92.4g of acrylic acid, and 3.76g of di-tert-butyl peroxide a mixture of monomers. The addition time of the monomer mixture was two hours, during which time the temperature of the batch was increased to 185°C. After the monomer addition was complete, stirring was continued at a temperature of 185° C. for an additional hour. Next, another 0.39 g of di-tert-butyl peroxide was charged, and stirring was continued for another 2 hour...

Abstract

This invention relates to novel carboxylic acid-modified vinylic polymeric compositions and the process for preparing them. In particular, the invention relates to novel carboxylic acid-modified vinylic polymeric compositions which exhibit properties that make them useful as support resins for producing polymer latices which can be employed in the formulation of various water-based coatings and inks, particularly flexographic inks. More particularly, these carboxylic acid-modified vinylic polymeric compositions are produced by the addition polymerization reaction of vinylic monomers in the presence of dimer acids, trimer acids, dimerized rosins, or mixtures thereof.

Description

technical field [0001] The present invention refers to a novel carboxylic acid modified vinyl polymer composition and its preparation method, especially the properties exhibited by it can be used as an auxiliary resin for the production of polymer latex carboxylic acid modified vinyl polymer composition, As a result, these latexes can be used to prepare various water-based coatings and inks, especially offset printing inks. Specifically, these carboxylic acid modified vinyl polymer compositions are prepared by addition polymerization of vinyl monomers in the presence of dimer acid, trimer acid, dimerized rosin, or mixtures thereof. Background technique [0002] Inks and overprint formulations used in a variety of printing applications are in high demand for certain high performance characteristics. Since typical surfactant-based emulsion polymerization products do not have the desired rheological properties for these applications, it is often necessary to add auxiliary resi...
