MONOBENZOATE ANALOGS USEFUL AS PLASTICIZERS IN PLASTISOL COMPOSITIONS
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. 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.

GLYCOL ETHER ARYL ESTER PLASTICIZER
Disclosed is the use of glycol ether aryl ester plasticizers as viscosity reducing agents in plastisols comprising di(2-ethylhexyl) terephthalate, 1,2-cyclohexane dicarboxylic acid diisononyl ester, or diisononyl phthalate as the primary plasticizer. The glycol ether aryl ester plasticizers improve viscosity and viscosity stability while maintaining or improving plastisol properties such as Shore A Hardness and fusion time.
