橡胶相的种类和用量对橡胶增韧聚合物如丙烯腈-丁二烯-苯乙烯（ABS）的性能有很大影响。橡胶相的表征是预测和控制ABS材料物理力学行为的有效手段。在这项工作中，不同的方法已被用来确定在ABS聚合物中的橡胶相的量。第一种方法是基于使用聚合物的特定步骤降解的热重分析法。在第二种方法中，利用傅里叶变换红外光谱中的特征吸收带制作校准曲线，以确定未知ABS样品的橡胶含量。第三种方法是基于ABS聚合物的热容随橡胶相含量的增加而变化。在第四种方法中，使用两步溶剂萃取，然后离心分离不同ABS样品的橡胶颗粒。采用分离法研究了橡胶颗粒的粒径及其分布。
The performances of rubber-toughened polymers like acrylonitrile-butadiene-styrene (ABS) are strongly affected by the type and amount of rubber phase. Characterization of rubber phase is an effective method to predict and control the physical and mechanical behaviors of ABS materials. In this work, different methods have been employed to determine the amount of rubber phase in ABS polymers. The first method was based on thermogravimetry using a particular step degradation of the polymer. In the second method, characteristic absorption bands in the Fourier transform infrared spectra were used to make a calibration curve to determine the rubber content of unknown ABS samples. The third method was based on variation of heat capacity of ABS polymers with increasing the rubber phase content. In the fourth method, a two-step solvent extraction followed by centrifuging was used to separate the rubber particles of different ABS samples. Separation of hardened rubber particles was used to study the size and size distribution of rubber particles.
