Calcium carbonate/natural rubber (NR) latex nanometer composites were prepared by adding nanometer CaCO 3 whose surface had been treated to natural rubber latex (NRL) before sulfuration. The physical, thermooxidative aging, and thermal degradation properties and the ultra‐microstructure were analyzed with a multipurpose material testing meter, a thermal analysis meter and a Philips XL‐30 SEM, respectively. The results showed that the structures and properties of nanometer composites could be clearly improved by NRL mixed with surface‐treated nanometer CaCO 3 . The physical properties of the nanometer composites were best when the content of surface treatment agent was 2.5% (to nanometer CaCO 3 ), the nanometer CaCO 3 /NRL content was 3:100, and the stirring time for treating the surface of the nanometer CaCO 3 was 20 min. Simultaneously, the thermooxidative aging resistance of the nanometer composites also was significantly improved. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 3442–3447, 2006
