WORKPIECE RETAINER AND METHOD FOR ATTACHING/DETACHING WORKPIECE BY USING THE SAME

摘要

A workpiece retainer includes an adhesive composition containing a pressure-sensitive adhesive and a side-chain crystallizable polymer so that the side-chain crystallizable polymer is present in an amount of about 1 % to about 30 % by weight based on the adhesive composition. The side-chain crystallizable polymer includes as a main component thereof an acrylic acid ester and/or methacrylic acid ester which has a straight-chain alkyl group including 16 or more carbon atoms as a side chain.
