主　　题：natural rubber nano CaCO3 nano composites in situ modification 

摘      要：Natural rubber (NR) was reinforced in situ with nano CaCO3 that had been modified with methacrylic acid (MAA)(M-CaCO3).The structures and properties of the resulting composites were studied using attenuated total reflection Fourier transform infrared spectroscopy(ATR-FTIR),scanning electron microscopy(SEM),and Mooney viscometer and mechanical *** results show that when NR is physically blended with CaCO3 and MAA,(Ca2+)-(–OOC) is formed in *** dicumyl peroxide (DCP) is added,the (Ca^2+)-(–OOC) self-homopolymerizes,and during the curing process poly-(Ca^2+)-(–OOC) is formed and grafts to the molecular chains of the NR via carbon-carbon double *** NR/M-CaCO3 composites formed have close interfacial interaction and are well *** with the NR composites reinforced with unmodified nano CaCO3,the NR/M-CaCO3 composites have very different cure characteristics,rheological behavior,and mechanical properties,and these characteristics and properties show a significant relationship with the loading of M-CaCO3.
