摘　　要：以通用型PVC树脂为基体,使用SBS-g-MAH通过双螺杆挤出机对其进行共混改性,研究了SBS-g-MAH的含量对PVC/SBS-g-MAH共混材料的力学性能影响。结果表明,SBS-g-MAH的引入可以提高PVC树脂的断裂伸长率、冲击强度,而材料的拉伸强度则降低。当SBS-g-MAH含量为5%时,断裂伸长率出现极大值;SBS-g-MAH含量为20%时,冲击强度出现极大值。General - purpose PVC resin was used for matrix and blended with SBS - g- MAtt for modification by twin - screw extruder, and the effects of the SBS - g- MAH content on mechanical properties of PVC/SBS - g - MAH blend materials were studied. The results showed that for the use of SBS - g - MAtt, such properties of PVC resin as the elongation at break and impact strength was raised, but tensile strength of materials decreased. When SBS - g - MAH content was 5 % （mass ratio）, the elongation at break was up to maximum value and when SBS - g - MAH content was 20%, impact strength reached maximum value.
