Modification of segmented polyurethane properties by copolymerizing with pendant functionalized diols

摘要

A functionalized polyurethane polymer is provided, the polymer defined by the formula; where each R′ is independently derived from a diisocyanate, where each R″ represents the soft segment of the polymer, where n is the number of repeat units within the soft segment of the polymer, where m is the number of repeating mer units in the polymer, where each E is a pendant-functionalized amide unit chain extender, wherein the nitrogen atom of the amide group is part of the polymer backbone. A method for preparing the polymer is also provided.
