%X The polydicyclopentadiene (PDCPD)/mesoporous molecular sieve SBA-15 composites were prepared by the methods of in situ polymerization and SBA-15 supported catalyst,in-situ polymerization.The mechanical performances of PDCPD/SBA-15 composites were studied.The reinforcing mechanism of mesoporous molecular sieve was investigated by XRD,TEM,TG,SEM,etc.The results showed that when the method of in situ polymerization was employed to prepare PDCPD/SBA-15 composites,the polymerization of dicyclopentadiene monomers was difficult to occur in the pores of SBA-15,causing that few molecular chains of PDCPD can form in the pores.The mechanical performances of composites improved weakly,compared with PDCPD,due to the weak interface compatibility between SBA-15 and PDCPD,and the conglomeration phenomenon of SBA-15 in PDCPD.The method of SBA-15 supported catalyst in situ polymerization is beneficial to the form of PDCPD molecular chains in the pores of SBA-15. The form of molecular chains in the pores can improve the interface interaction between SBA-15 surface and PDCPD molecular chains,prevent the conglomeration of SBA-15 particles in PDCPD,and enhance the tensile strength and heat-stability of composites greatly.Compared with PDCPD,the tensile strength of PDCPD/SBA-15 improves by 24.5% with 2% SBA-15 content.
