Title:
TEMPERATURE-SENSITIVE ADHESIVE COMPOSITION
Document Type and Number:
Japanese Patent JP3541194
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a temperature-sensitive adhesive composition containing a crystalline polymer.
SOLUTION: This temperature-sensitive adhesive composition comprises a side chain-crystalline polymer. The side chain-crystalline polymer comprises (a) side chain-crystalline recurring units derived from an acrylate or methacrylate ester and (b) side chain-noncrystalline recurring units derived from an acrylate or methacrylate ester, has almost no adhesiveness below the melt starting temperature T0, varies to have adhesiveness by heating from a temperature below T0 to a temperature above the peak melting temperature Tm and varies to lose adhesiveness by cooling from a temperature above Tm to a temperature below T0. The composition is applied to immobilize a main body element on a substrate at the temperature above Tm and then peel the main body element from the substrate by cooling below T0.
