MONOBENZOATE ANALOGS USEFUL AS PLASTICIZERS IN PLASTISOL COMPOSITIONS
First Claim
1. A plastisol composition comprising:
- polymer particles dispersed in a plasticizer, wherein the plasticizer contains a primary plasticizer and at least one other plasticizer comprising;
2-methyl-3-phenylpropyl benzoate, 2-phenylethyl 2-phenylacetate, benzyl 3-phenylpropanoate, or benzyl 2-methyl-3-phenyl-propanoate, present in amounts ranging from about 2 to about 20 parts per 100 parts by weight of the polymer particles.

Abstract
Unique 3-PPB monobenzoate analogs useful as plasticizers in polymeric dispersions, such as plastisols, melt compounds, and adhesives among other applications. The analogs are structurally similar to and/or derived from 3-phenylpropyl benzoate and heretofore were not known for use in industrial applications, particularly not as a plasticizer in polymeric applications including without limitation plastisols and adhesives. Depending on the application, the advantages rendered by the use of the inventive monobenzoate analogs include, among other things, excellent solvating properties and rheology, low viscosity and significantly improved viscosity over time, comparable or improved Tg suppression, set and open times, as well as health, safety and environmental advantages, over traditional plasticizers.

-
(a) polymer particles dispersed in a plasticizer; and (b) a plasticizer comprising; (i) at least one plasticizer comprising a phthalate, a 1,2-cyclohexane dicarboxylate, or a dibenzoate plasticizer, or mixtures thereof, and, (ii) at least one other plasticizer comprising;
2-methyl-3-phenylpropyl benzoate, 2-phenylethyl 2-phenylacetate, benzyl 3-phenylpropanoate, or benzyl 2-methyl-3-phenyl-propanoate,wherein the total plasticizer content of the plastisol ranges from about 20 to about 80 parts per one hundred parts by weight of polymer particles, and wherein the 2-methyl-3-phenylpropyl benzoate, 2-phenylethyl 2-phenylacetate, benzyl 3-phenylpropanoate, or benzyl 2-methyl-3-phenyl-propanoate are present in amounts ranging from about 5% to about 20% of the total plasticizer content.
