PRESSURE-SENSITIVE ADHESIVES PREPARED FROM DEGRADABLE MONOMERS AND POLYMERS

摘要

Pressure-sensitive adhesives that have good performance characteristics under typical use conditions and that later can be degraded and/or removed readily under basic conditions are provided. More specifically, the pressure-sensitive adhesives contain a copolymeric (meth)acrylic-based elastomeric material prepared from a polymerizable material that contains a (meth)acrylate monomer having both a (meth)acryloyl group plus an ester linkage that is not part of a (meth)acryloyl group.

1. A pressure-sensitive adhesive comprising a copolymeric (meth)acrylic-based elastomeric material comprising a reaction product of polymerizable material comprising:
(a) a first monomer that is of Formula (I) wherein
R1 is an alkyl, aryl, or a combination thereof;Y is a branched or linear alkylene of formula —Cn(R2)2n—;R2 is hydrogen or alkyl;n is an integer in a range of 1 to 12;R3 is hydrogen or methyl; and (b) a second monomer having an ethylenically unsaturated group.
