Abstract
A modified pressure sensitive adhesive (PSA) is produced by polymerizing at least one ethylenically unsaturated monomer to form a base polymer and reacting the base polymer with a modifying polymer comprising units derived from a n-vinyl lactam to thereby produce a modified polymer. The modified polymer can be used to form modified PSAs having improved adhesion properties over PSAs formed from the unmodified base polymer.
