%X Aliphatic polyether-based polyurethane(PU) elastomers with hyperbranched polyester segments were synthesized by prepolymer process from polytetramethylene ether glycol,hydroxyl-terminated hyperbranched polyester(HB-20),IPDI and 1,4-butanediol.The crosslinking density of the PU elastomer was calculated by using the Flory-Rehner equation.The degree of hydrogen bonding,the microstructure and the morphologies of these PU materials were characterized by means of FTIR,WAXD and DSC,respectively.The experimental re...
