HEAT-SENSITIVE ADHESIVE AND HEAT-SENSITIVE ADHESIVE TAPE

摘要

The disclosed heat-sensitive adhesive comprises a side chain crystalline polymer and exhibits adhesive strength at temperatures above the melting point of the side chain crystalline polymer. The side chain crystalline polymer is composed of a crosslinked polymer obtained by adding a metal chelate compound to the side chain crystalline polymer and carrying out a crosslinking reaction. The side chain crystalline polymer crystallizes at a temperature less than the melting point and demonstrates fluidity at temperatures above the melting point. The disclosed heat-sensitive adhesive tape is provided with an adhesive layer composed of the heat-sensitive adhesive on one or both sides of a base material film.
