TEMPERATURE-SENSITIVE ADHESIVE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a temperature-sensitive adhesive that contains a side-chain crystalline polymer having a high molecular weight and a narrow molecular weight distribution (Mw/Mn) and is easily produced and a method for producing the same.SOLUTION: A temperature-sensitive adhesive includes a side-chain crystalline polymer and decreases an adhesive force at a temperature lower than the melting point of the side-chain crystalline polymer, wherein the side-chain crystalline polymer comprises a polymer obtained by polymerizing a monomer constituting the side-chain crystalline polymer under pressure by atom transfer radical polymerization (ATRP). A method for producing the same is provided. When the monomer is polymerized under pressure by ATRP, the side-chain crystalline polymer can have a high molecular weight and a narrow molecular weight distribution (Mw/Mn) while shortening the reaction time.
