中文摘要	Free-radical melt grafting of the multi-monomre system of maleic anhydride(MAH)/styrene( SO onto ABS resin was studied using a Hakke rheometer. The maximum MAH graft degree was obtained when the molar ratio of MAH to St was approximately 1 : 1. The addition of St, an assisting monomer, improved the grafting reactivity of MAH,and St also reacted with MAH to form the St-MAH copolymer(SMA) before the two monomers grafted onto BAS. The site of grafting is mainly at the double bonds of ABS. ABS-g-(MAH-co-St) was used as a precursor on in-situ compatibilizer for incompatible blend of PA6 and ABS. The changes in morphologies of PA6/ABS/ABS-g(MAH-co-St) blends with different contents of ABS-g-(MAH-co-St) were investigated using SEM. The addition of ABS-g-(MAH-co-St) markedly improved the morphologies of the blends,and an uniform and fine dispersed phase was obseved with size being about 0.1 mu m for a PA6/ABS-g-(MAH-co-St)(70/30) blend. The addition of ABS-g(MAH-co-St) also greatly improved the mechanical properties of PA6/ABS blends. The Izod impact strength of the blends greatly increased with increasing the content of ABS-g-(MAH-co-St) in the blends,and the tensile strength of the blends also increased. The PA6/ABS blends with balanced mechanical properties could be obtained by addition of ABS-g-(MAH-co-St).
