A pressure-sensitive adhesive polymer comprising a reaction product of a C1
to C20 alkyl (meth)acrylate, an ethylenically unsaturated carboxylic
acid, a C2 to C8 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.
