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.
