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.

Monobenzoate analogs useful as plasticizers in plastisol compositions

Polyester plasticizer compositions for adhesives, caulk, sealants, vinyl and other polymeric compositions comprising low molecular weight oligomeric dibenzoates prepared by end-capping a polyester plasticizer, having alternating units of glycols or diols and dibasic acids, with benzoic acid. Methods for preparing oligomeric dibenzoates include steps to reduce or eliminate residual hydroxyl content and improve plasticizer performance by adding acetic anhydride are also disclosed. Propylene glycol adipate and propylene glycol succinate polyesters with benzoic acid end-caps are particularly useful, as are hybrid benzoate/acetate end-capped polyesters formed in the process with acetic anhydride. Caulks, adhesives, sealants, and vinyl compositions comprising the oligomeric end-capped polyesters of the invention are also contemplated.
