摘要

<正> Cure characteristics of hydroxyl terminated polybutadiene （HTPB） prepolymer with avariety of blocked toluene diisocyanate （TDI） in the presence of triethylamine （TEA） andchloroacetic acid catalyst are reported. Phenol

thiophenol

p-chloropheno1

p-nitrophenol

p-cresol

resorcinol

naphthols

caprolactam and butylated-hydroxytoluene were used as blockingagents. Viscosity measurements have been carried out using a mixture of HTPB and blocked TDIin cyclohexanone in the presence of the catalysts at 50℃ and 60℃ using Haake rotational vis-cometer. Viscosity measurements have also been carried out with 50% solids such as ammonium sulphate along with HTPB and TDI adduct.
