摘要

The hydroxyl-terminated polybutadiene (HTPB) possessing high content of 1

4-units was synthesized by anionic polymerization of butadiene

using alkyllithium containing silicon-protected hydroxyl group as initiator and cyclohexane as solvent. The polymers were characterized by GPC

IR and 1H-NMR. The mechanical properties of cured films were also evaluated. The results show that the content of 1

4-units for HTPBs made by anionic polymerization reaches up to 90%. The molecular weight distribution is very narrow (≤ 1.05). The functionality of hydroxyl groups approaches 2. Compared with free radical HTPB

the elongation at break of anionic HTPB films increased by 70%

while the tensile strength remained nearly unchanged. This new HTPB can be very useful in solid propellant.
