Poly(n-Butyl Acrylate)/Polyurethane based on castor oil semi-SEN(PnBA/COPU) has been synthesized by simultaneous prepolymerization and characterized by TBA
SEM and tensile test. The results show that some mechanical propertjes
such as Young's modulus
tensile strength and elongation at break
increase synergistically at PnBA/COPU = 10/90
whereas the fracture energy shows the maximum at PnBA/COPU = 50/50. The semi-SEN is a partial compatible system and two-phase structure with domain size of about 800A is observed.The effect of morphology on the properties of the semi-SEN has been discussed.
