少量的橡胶是如何使脆性塑料的抗断裂性显著提高的？橡胶增韧的机理是什么？这些基本问题的答案远不明显。第一个令人满意的增韧理论是在1964年提出的，距离Ostromislensky最初的发现已经过去了近40年，距离HIPS的商业化引入已经过去了15年。自1964年以来，该学科已发展到可以构建定量理论的阶段，但关于结构与断裂阻力之间的关系仍有许多悬而未决的问题。本章介绍了橡胶增韧的一些定性和定量理论，并讨论了尚未解决的问题。
How do small quantities of rubber produce such dramatic increases in the fracture resistance of brittle plastics? What is the mechanism of rubber toughening? The answer to these fundamental questions is far from obvious. The first satisfactory theory of toughening was advanced in 1964, almost 40 years after Ostromislensky’s original discovery, and 15 years after the commercial introduction of HIPS. Since 1964, the subject has developed to the stage at which quantitative theories can be constructed, but there are still many outstanding questions concerning the relationship between structure and fracture resistance. This chapter presents some of the qualitative and quantitative theories of rubber toughening, and discusses the problems that remain unresolved.
