The Investigation on Polyurethane and Epoxyresin Interpenetrating Polymer Networks

Abstract

Abstract: In this paper, the synthesis of interpenetrating polymer nelworks(IPN) based on polyurethane and epoxide by simultaneous polymerization, the influence of various component on their morphology, gh-ss transition behavior,mechanical properties and thermostability are reported. The results show that PU/EP = 25/75 exhibited the best, mechanical properties and thermostability due to the high degree of interpenetration among the networks. PU/Ep = 50/50 exhibited obvious phase separation and the poorest mechnical properties.

Key words: PU/EP, Interpenetrating
