我们将先前报道的苯乙烯辐射诱导离子聚合的研究扩展到更高的剂量率，并覆盖了0至50°C的温度范围。0°C时的数据与威廉姆斯、Okamura等人提出的机理惊人地一致（高达106 rad/hr）;另一方面，最高纯度的苯乙烯随着温度变化表现出非常复杂的行为，这与该机理不一致。这些明显的异常提出和讨论。数据还提出了在纯苯乙烯中加入干氧或脱气水的影响。
We have extended our previously reported studies on the radiation-induced ionic polymerization of styrene to higher dose rates and have covered a temperature range between 0 and 50°C. The data at 0°C are in striking agreement (up to 106 rad/hr) with the mechanism proposed by Williams, Okamura, et al.; on the other hand, styrene of the highest purity exhibits a very complex behavior with temperature variations, which does not agree with this mechanism. These apparent anomalies are presented and discussed. Data are also presented on the effects of adding dry oxygen or degassed water to pure styrene.
