Method to improve cold flow resistance of polymers

摘要

A method for preparing a polymeric composition, the method comprising providing a polymer cement including a polymer and a solvent, introducing an acetal or ketal of an alditol with the polymer cement, and isolating at least a portion of the polymer and the acetal or ketal of an alditol from the solvent to provide a polymeric composition including the polymer and the acetal or ketal of an alditol.
