Abstract

A systematic study was conducted on the effect of hard segment molecular weight on solution and bulk properties of ether based thermoplastic polyurethanes (TPUs). The purpose of this study is to provide a roadmap to deliver the desired end-use performance of a polyurethane product based on the optimal design of the starting materials using a bottom-up approach [1]. We found the role of nanosized domains induced by hard segment molecular weight significantly impacts the solution, rheological and bulk properties of TPU. Also, at a limiting weight fraction of the hard segment, the increase in weight fraction of the hard segment has a diminishing effect for both solution and bulk properties. Highlights of the experimental findings in the TPU synthesis and characterization of solution properties are discussed.
