Abstract

This study focuses on the microwave-assisted synthesis of hydroxyl-terminated polybutadiene (HTPB) based polyurethanes. Driven by microwave irradiation, the synthetic rate of HTPB based polyurethanes is three times faster than the synthesis operated by traditional oil-bath heating. Though the synthesis time is significantly decreased, polyurethanes synthesized with microwave irradiation exhibit comparable mechanical performances to the similar polyurethanes obtained by traditional oil-bath heating. The tensile strength and Young’s modulus of polyurethanes synthesized with microwave irradiation are also higher than conventional method. HTPB based polyurethanes also exhibit excellent thermal stability and hydrolysis resistance. Our research suggests a fast and interesting way to synthesize HTPB based polyurethanes.
