Abstract锛� Acrylonitrile-butadiene-styrene(ABS)/polyethylene terephthalate(PET)/polyethylene terephthalate-1,4-cyclohexanedimethanol (PETG) blends were toughened by ABS high rubber powder(ABSHR). The influence of the amount of ABSHR on the mechanical properties, thermal stability, heat resistance and hardness of the alloy was discussed. Meanwhile, the cross section of the alloy was characterized by scanning electron microscopy (SEM). The results show that the impact strength and elongation at break increase with the increase of the amount of ABSHR.The tensile strength and bending strength decrease, but has little effect on the thermal stability,and the heat resistance and hardness decrease slightly with the increase of ABSHR. SEM shows that a large amount of debation is produced and a large amount of impact energy is absorbed when the alloy is broken.

Abstract锛� A series of ABS (acrylonitrile-butadiene-styrene) grafted copolymers with different coreshell ratio were synthesized by changing the feeding proportion of polybutadiene (PB) and comonomer. And ABS resin was successfully prepared by means of melt blending ABS grafted copolymer with SAN copolymer. The structure and perbance of the blends (ABS resin) were investigated by using DMA and SEM. It is found that with the increase of core-shell ratio of ABS grafted copolymer, the Izod impact strength of the blends increases first and then decreases,but the tensile behavior almost unchanges. The (tan未)max of rubber phase depends on the coreshell ratio of ABS grafted copolymers. The blends prepared by ABS grafted copolymer with 70/30 core-shell ratio fracture in ductile mode, which is consistent with the mechanical test results.

Abstract锛� ABS composites were prepared by adding different modifiers in acrylonitrile butadiene styrene copolymer(ABS). The influence rules of mechanical property of different modifiers in ABS composites were analyzed by dynamic mechanical analysis, scanning electron microscope, and other testing technologies. The results show that comparing with unmodified ABS materials, the tensile strength of ABS/SMA composites is 51.2 MPa, increases by 6.8%; SMA as compatibilizer can improve the interfacial bonding strength between TPU and ABS, and the mechanical properties of ABS/SMA/TPU composites can be improved, and the tensile strength of is 52.2 MPa. The impact strength of ABS/SMA/ABS high rubber composites is 29.3 kJ/m2, which increases by 34.4%, and the comprehensive mechanical properties of composites are ideal.
