Abstract: The invention provides a plasticizer for use in plastic materials such as polyvinyl chloride. The plasticizer is a blend of di-(2-ethylhexyl) terephthalate (DOTP) and 2-ethylhexyl methyl terephthalate (MOTP). The blend of di-(2-ethylhexyl) terephthalate and 2-ethylhexyl methyl terephthalate provides a non-ortho-phthalate alternative to plasticizers such as diisononyl phthalate and also produces good fusion temperature, gelation point, plastisol viscosity, efficiency, plasticizer compatibility, and drying time performance.

Abstract: The present application discloses plasticizer compositions comprising: (I) a compound of formula I: wherein R1, R2, and n are defined herein. The application also discloses resin compositions comprising the compound of formula I.

Abstract: 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.

Abstract: The present application discloses novel cyclohexane dicarboxylate mixed esters of formula I: wherein R1, R2, and n are defined herein. The mixed esters are useful as plasticizers. The application also discloses resin compositions comprising the cyclohexane dicarboxylate mixed esters of formula I.

Abstract: The present application discloses low cost plastisols with high filler loading and gel points below 77° C.

Abstract: A plasticizer has been identified that improves compatibility in PVC formulations where secondary plasticizers and viscosity modifiers are present. In general, 1,2- or 1,4-dialkyl cyclohexane dicarboxylate plasticizers exhibit poor compatibility, as evidenced by increased exudation, in the presence of secondary plasticizers, i.e. chlorinated paraffins and hydrocarbon-based viscosity modifiers. We have found that bis 1,4-(2-ethylhexyl) cyclohexane dicarboxylate (DOCH) displays the opposite behavior, showing greater compatibility in the presence of these compounds than most other 1,2- or 1,4-dialkyl cyclohexane dicarboxylate derivatives (i.e. DINCH) or blends of fast-fuser/general purpose plasticizers.
