Abstract

Effects of hyperbranched polyesters on kinetics of the reaction between hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) were investigated. HTPB and IPDI were in-situ cured in the presence of two different hyperbranched polyesters, stearic acid ester-terminated hyperbranched polyester (SHPE) and acetate-terminated hyperbranched polyester (AHPE). The curing processes were monitored by quantitative Fourier transform infrared (FTIR) spectroscopy. The results showed the stearic acid ester-terminated hyperbranched polyester had catalytic effects on the reaction between HTPB and IPDI, while acetate-terminated hyperbranched polyester did not have an influence on the reaction between HTPB and IPDI.
