PVC plasticizer from trimethylolpropane trioleate: synthesis, properties, and application

Abstract A new oleic acid derivative plasticizer, epoxidized trimethylolpropane trioleate (EPO), has been synthesized and its application in PVC formulations compared with di(2-ethylhexyl) 1,2-cyclohexanoate (DOCH/DEHCH), a commercial phthalate-free plasticizer of petrochemical origin. EPO their blends DOCH were added to resin (50 PHR) the plasticized characterized by thermal mechanical measurements. demonstrated good compatibility improving stability elongation at break. Due high molar mass, slight increase glass transition temperature hardness was observed as content blend increased. The results indicate that is potential for when pure and, replacing 50% DOCH, compound shows similar properties but better break stability.
