Abstract

A simple oligomeric A 2 + B 2 approach was described for the preparation of segmented, hyperbranched polyureas and poly(urethane urea). The approach utilized an isocyanate end-capped polyether as an oligomeric A 2 monomer and B 3 triamine monomer. The approach can be extended to a large number of telechelic oligomers including poly(dimethylsiloxane) (PDMS) or poly (ethylene glycol) and trifunctional polymer (B 3) to prepare polymeric materials. The similarity in soft segment glass transition behavior and strain hardening character of the hyperbranched systems suggested considerable promise for future applications.
