Studies on Poly(n-butyl Acrylate)/Polyurethane Based on Castor Oil SEN (Ⅱ)——Full-SEN

Abstract

Abstract: Poly(N-butyl acrylate)/polyurethane based on castor oil (PnBA/COPU) full-SEN has been synthesized by simultaneous prepolymerization and the tensile, swelling and transition behavior, and morphology of full-SEN were characterized.The effect of composition on tensile strength, Young's modulus and elongation at break of full-SEN is similar to that of semi-SEN, but the values are higher than those of semi-SEN's as the weight fraction of PnBA is higher than 0.5.The micrographs of full-SEN show a two-phase morphology and the compatibility of the two components in full-SEN is much higher than semi-SEN.

Key words: Poly(n-butyl acrylate), Polyurethane based on castor oil, Full-SEN, Tensile property, Morphology
