| 摘要 |
A pressure-sensitive adhesive polymer comprising a reaction product of a C<SUB>1 </SUB>to C<SUB>20 </SUB>alkyl (meth)acrylate, an ethylenically unsaturated carboxylic acid, a C<SUB>2 </SUB>to C<SUB>8 </SUB>hydroxyalkyl (meth)acrylate, a vinyl aromatic, optionally a ethylenically unsaturated monomer containing sulfonic acid, and optionally a vinyl ester of a carboxylic acid. The pressure-sensitive adhesive polymer can provide adhesion and cohesion in a temperature range from -30° C. to 50° C. for the All-temperature pressure-sensitive adhesive market.
