摘　　要：向PVC/ABS合金体系中分别加入AS树脂、MBS树脂、EP和DOP,实验结果发现,加入适量的AS、EP,体系韧性明显下降,弯曲强度、弯曲模量有所提高,MBS的加入提高了PVC/ABS合金的冲击强度,但是弯曲强度和弯曲模量下降明显,DOP的加入使得PVC/ABS合金体系的冲击强度、弯曲强度及弯曲模量都有明显下降,降低了体系的力学性能。The AS resin, MBS resin, EP and DOP were added into the PVC / ABS alloy system. The results showed that the addition of the appropriate amount of AS resin, EP, the toughness of the system decreased obviously, the flexural strength and flexural modulus increased. MBS resin to improve the PVC / ABS alloy impact strength, but the bending strength and bending modulus decreased significantly, The impact strength, flexural strength and flexural modulus of PVC / ABS alloy system are obviously decreased by the addition of DOP, which reduces the mechanical properties of the system.
