Chlorinated Ester Polyvinyl-Chloride Secondary Plasticizer and Related Methods

Abstract

A composition having polyvinylchloride; and a chlorinated ester having the chemical structure: wherein R1 is a C6-22 chlorinated-hydrocarbon moiety, wherein R2 is a C1-C18 hydrocarbon moiety, wherein n is 1, 2, 3, or 4, wherein if n is greater than 1, each R1 is the same or different; and wherein the chlorinated ester is 15-70% by weight chlorine; wherein the chlorinated ester is a product of a process that uses fatty-acid-ester reactants having less than two C═C double bonds; and wherein the chlorinated ester is a product of a process that does not use fatty-acid-ester reactants having two or more C═C double bonds.
