Summary: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.
