Pressure sensitive adhesive compositions and methods for preparing same

A method for making a polymerization product comprising

• reacting a monomer mixture comprising the following components:
• (a) one or more alkyl ester of (meth)acrylic acid or cyclic hydrocarbon acrylate, wherein the one or more alkyl ester of (meth)acrylic acid or cyclic hydrocarbon acrylate comprises at least one low Tg monomer that produces a homopolymer having a Tg of less than −20° C., and wherein the sum of all of the one or more alkyl ester of (meth)acrylic acid or cyclic hydrocarbon acrylate is more than 30 wt. %;
• (b) 0.1 to less than 25 wt. % of a vinyl ester of versatic acid;
• (c) 0.1 to 8 wt. % of at least one hydroxyl functional (meth)acrylate monomer, or 0.1 to 10 wt. % of at least one epoxy functional (meth)acrylate monomer;
• (d) 0.05 to 3 wt. % of least one ureido substituted ethylenically unsaturated monomer;
• (e) optionally 0 to 6 wt. % at least one ethylenically unsaturated carboxylic acid;
• (f) optionally 0 to 20 wt. % of at least one vinyl aromatic monomer;
• and
• (g) optionally 0 to 25 wt. % of at least one ethylenically unsaturated monomer different from monomers (a) to (f),
• wherein the wt. % is based on the total weight of the monomer mixture.
