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.
Claims12
A method for forming a pressure sensitive adhesive, the method comprising:
- (a) providing at least two substances selected from the group consisting of epoxidized fatty esters and (meth)acrylic copolymers;
- and
- (b) copolymerizing the at least two substances using organic solvent-based polymerization or on web polymerization.
A method for forming a pressure sensitive adhesive, the method comprising:
- (a) providing at least two substances selected from the group consisting of an acrylated epoxidized triglyceride, an acrylic copolymer, a fatty acid based monomer produced by the reaction of an acid group of a fatty acid and an epoxy group of glycidylmethacrylate, and a (meth)acrylic monomer;
- and
- (b) copolymerizing the at least two substances using organic solvent-based polymerization or on web polymerization;
- wherein the step of copolymerizing the at least two substances includes photocatalyzed cationic polymerization.
A method for forming a pressure sensitive adhesive, the method comprising:
- (a) providing a conjugated linoleic acid;
- and
- (b) copolymerizing the conjugated linoleic acid with an acrylic monomer using organic solvent-based polymerization or on web polymerization.
