TEMPERATURE SENSITIVE ADHESIVE

摘要

This temperature sensitive adhesive includes a side chain crystalline polymer obtained by polymerizing (meth)acrylate having a straight chain alkyl group with at least 16 carbon atoms, and adhesion of the temperature sensitive adhesive decreases at a temperature less than the melting point of the side chain crystalline polymer. The side chain crystalline polymer is composed of a copolymer obtained by further polymerizing a reactive polysiloxane compound, and the ratio of the (meth)acrylate having a straight chain alkyl group with at least 16 carbon atoms to the reactive polysiloxane compound is (meth)acrylate having a straight chain alkyl group with at least 16 carbon atoms:reactive polysiloxane compound=91:9 to 99:1, by weight.
