ACRYLIC COMPOSITIONS FOR ADHERING TO LOW SURFACE ENERGY SUBTRATES

摘要

Abstract In general, the invention features a pressure sensitive adhesive that comprises the reaction product of: (a) from about 25 to about 95 parts by weight of at least one acrylic acid ester of a monohydric alcohol whose homopolymer has a Tg less than 00C, (b) from 0 to about 75 parts by weight of at least one non-polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of no greater than 10.50 and a Tg greater than 15*C; and (c) from about 5 to about 35 parts by weight of at least one polar ethylenically unsaturated monomer whose homopolymer has a solubility parameter of greater than 10.50 and a Tg greater than 15*C. The pressure sensitive adhesives adhere to substrates having a low surface energy and/or high surface energy. 6564979 2 (GHMatters) P89889.AU.1 WILSONC
