Embodiment

[0059] Suitable polycaprolactone particles of the present invention can be produced according to the method disclosed in US Patent No. 3,632,669. The resulting spray-dried powder is mixed with fillers and pigments, a portion of the plasticizing fragrance material (such as essential oils) is added, followed by the remainder of the fragrance plasticizer premixed with the thixotropic gelling agent. The obtained mass can be molded into blocks or sheets.

[0060] Sufficient shear is required to disperse the plastisol components. At the same time, the duration of the cycle and the shear rate need to be controlled to prevent the generation of excess heat that could prematurely initiate the gelation reaction. It is desirable to keep the temperature below 20°C (eg, by using a cooling jacket, short mixing cycles, and / or limiting mixing rates). Compositions whose viscosity decreases with increasing shear rate can be efficiently prepared at higher speeds. However, this can lead to seve...

Abstract

Polymer compositions suitable for modeling are provided as plastisols with a high content of volatile substances, such as bactericidal, aromatizing, and / or flavoring volatiles. Such plastisols are provided by mixing a lyophilic polyamide or lyophilic complex polyester with a plasticizer of moderate to low polarity that includes a bactericidal, aromatizing, and / or flavoring components, such as an essential oil. After mixing, additives such as fillers, pigments, and gelling agents are added. A solid plastic is produced by heating the formed plastisol to a gelation temperature and then heating to a solution temperature to generate a solid plastic with enduring bactericidal activity, scent, and / or flavor.

Description

[0001] This application claims priority to U.S. Provisional Application No. 62 / 741425, filed October 4, 2018. These and all other cited external materials are hereby incorporated by reference in their entirety. In the event that a definition or use of a term in a reference incorporated by reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein is deemed to control. technical field [0002] The present invention relates to polymer compositions for modeling, in particular to plastisols with a high content of volatile substances (eg bactericidal, aromatizing substances, flavoring volatiles) for modeling. Fields of application of this plastisol are the production of modeling materials for children's play, prototyping, modeling of aromatic products, antiseptic products, products containing insect repellants or attractants. Examples of such articles include educational toys, stucco moldings, cosmetic implemen...
