25 Claims

1. A method for making a plasticized polymer comprising the step of:

polymerizing a polymerizable monomer in a reaction medium comprising a plasticizer and in the presence of a catalyst system for a time and temperature sufficient to form a plasticizer system comprising the plasticized polymer, wherein the plasticizer system further comprises at least 25 wt % of the plasticizer and is suitable for use as a component in an adhesive, wherein:

the plasticizer is selected from the group consisting of mineral oil, liquid polybutene, hydrocarbon oil, synthetic oil, a dibenzoate, a phosphate, a phthalate ester, and an ester of a monoglycol or a polyglycol, and the reaction medium contains less than 10 wt % solvent.
