<p><P>PROBLEM TO BE SOLVED: To provide a self-adhesive sheet which has high fixing force and elastic modulus at fixing an adherend, is easily detached and hardly generates adhesive deposit. <P>SOLUTION: This self-adhesive sheet has a thickness of 10-70μm, and includes a side-chain crystalline polymer and a foaming agent in an amount of 10-110 pts.wt. to 100 pts.wt. of the side-chain crystalline polymer. The side-chain crystalline polymer has a melting point of 30°C or higher but lower than the foaming temperature of the foaming agent, crystallizes at a temperature lower than the melting point and exhibits fluidity at a temperature of the melting point or higher, and has a weight-average molecular weight of 10,000-700,000. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
