BLOCK COPOLYMER MELT-PROCESSABLE COMPOSITION, METHOD OF PREPARING THE SAME, AND ARTICLE FROM THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a useful pressure-sensitive adhesive. SOLUTION: In a melt-processable poly(meth)acrylate composition containing a block copolymer, the block copolymer contains at least one high glass transition temperature copolymer terminal block and at least one low glass transition temperature polymer block, the high glass transition temperature copolymer block contains a first monomer unit and a second monomer unit, the second monomer unit raises or drops the melt flow temperature of the block copolymer as compared with a similar block copolymer containing no second monomer unit and the melt flow temperature of the block copolymer lies in the range of 50 to 250°C.
