The dynamic mechanical properties of the copolymer networks,AB-crosslinked polymers (ABCP), from a castor oil polyurethane(COPU)and poly(butyl methactylate) (PBMA) were quite different from that of IPN which have the similar composition to ABCP.In the case of COPU/PBMA ABCP,the damping peaks of the two components shift inward and overlap each other,which reveals that the polymer system is partially compatible.However, the damping peak of COPU/PBMA 1PN is a wide plateau.The electron micrographs show the larger domain sizes in IPN than in ABCP.The iesults indicates that the effect of chemical crosslinking on the compatibility is more notable than the physical entanglement. ABCP's from COPU/PST and COPU/PMMA are partially compatible like that of COPU/PBMA,while COPU/PMA and COPU/PBA aro completely compatible.
