摘要
对影响本体聚苯乙烯树脂 (PS)冲击强度的因素 ,如相对分子质量、单体转化率、加工工艺、测试环境及样条宽度等进行了讨论 ,对相关标准的制订及塑料制品的成型加工提出了几点建议。
The factors affecting the impact strength of bulk polystyrene resin,such as relative molecular mass,monomer conversion,processing technique,test environment and sample width,were discussed.Some suggestions were made for the making of correlated standards and injection moulding of plastic products.
