Ternary composites of glass fiber‐reinforced poly( p ‐phenylene sulfide) (PPS/GF) filled with nanometric calcium carbonate (nano‐CaCO 3 ) were prepared by means of a twin‐screw extruder. The nano‐CaCO 3 surface was treated with stearate and treated with titanate, the composites being called SI composite system and SII composite system, respectively. The crystallization and heatproof properties of the PPS/GF/nano‐CaCO 3 composites were measured using a differential scanning calorimeter, to investigate the influence of the nanometric filler content on the crystallinity. The results show that the variation of the starting crystallization temperature, crystallization temperature and crystallinity with an increase of the particle weigh fraction (ϕ f ) of SI composite system is different from that of SII composite system. When ϕ f is less than 4 wt%, the crystallinity of the two composite systems increases and then decreases slightly with increasing ϕ f . Moreover, the crystallization behavior and mechanisms are discussed. Copyright © 2011 Society of Chemical Industry
