摘　　要：研究了复合橡胶对高抗冲聚苯乙烯(HIPS)结构与性能的影响,并用透射电子显微镜对HIPS进行了表征。结果表明:低顺聚丁二烯橡胶(简称低顺橡胶)能增加HIPS橡胶相体积分数,使橡胶粒子形态分布更均匀;高顺聚丁二烯橡胶(简称高顺橡胶)有利于提高产品的韧性;低顺橡胶对HIPS弯曲强度和拉伸强度的增加贡献更大;采用高顺橡胶与低顺橡胶复合,能够协调HIPS的韧性、弯曲强度和拉伸强度。The effect of compounded rubber on the structure and properties of high impact polystyrene(HIPS)was observed,and HIPS samples were characterized by transmission electron microscope.The results show that low cis-polybutadiene rubber(low cis-rubber)can increase the phase volume fraction of HIPS and make the morphology distribution of rubber particles more uniform.High cis-polybutadiene rubber(high cisrubber)can improve the toughness of the product,while low cis-rubber contributes more to the increase of bending strength and tensile strength of the product.High cis-rubber and low cis-rubber can be combined to coordinate the toughness,bending strength and tensile strength of HIPS.
