Abstract
A method for forming a pressure sensitive adhesive including providing a substance that is an epoxidized triglyceride or an epoxidized fatty ester, and polymerizing the substance. A pressure sensitive adhesive can be formed by copolymerizing at least two substances that can be an epoxidized triglyceride, epoxidized fatty ester, or (meth)acrylic copolymer. In yet another method, the at least two substances can be an acrylated epoxidized triglyceride, acrylic copolymer, fatty acid based monomer produced by the reaction of an acid group of a fatty acid and an epoxy group of glycidylmethacrylate, or (meth)acrylic monomer.
