PRESSURE SENSITIVE ADHESIVE AND METHOD OF SYNTHESIZING POLYMER USED FOR THE SAME

摘要

A method of synthesizing an acrylic polymer used for a pressure sensitive adhesive includes steps as follows: polymerizing one or more acrylic monomers in the presence of a first initiator to obtain an acrylic prepolymer; and polymerizing the acrylic prepolymer and one or more silane coupling agents in the presence of a second initiator to obtain the acrylic polymer.
