Acrylonitrile-styrene-butadiene high glue powder(ABSHR)grafted maleic anhydride(MAH)was studied by solution method.The structure of ABSHR-g-MA was characterized by infrared spectroscopy.Effect of the amount of MAH,BPO,ABSHR,reaction temperature and reaction time on the ABSHR-g-MA grafting rate and the effect of ABSHR-g-MA as compatibilizer on the properties of ABS/PET alloy were investigated.The results showed that the grafting rate of ABSHR-g-MA increased with the increase of MAH and BPO,but the increase of grafting rate was slightly lower when the amount of MAH was more;increased reaction temperature and prolonged reaction time properly were beneficial to grafting reaction;using ABSHR-g-MA as ABS/PET alloy compatibilizer,the notched impact strength and elongation at break increased obviously with the increase of ABSHR-g-MA grafting rate,which increased by 127% and 121% respectively,while the tensile strength and flexural strength decreased slightly;the heat resistance was increased and the melt flow rate was reduced with the increase of ABSHR-g-MA grafting rate.
