Staudinger等人多年前进行了二乙烯基苯对苯乙烯聚合影响的实验。（4）和类似的研究最近发表的C 'h。XYalling（7）.主要结果是仅含百分之几交联剂的共聚物不溶于苯、甲苯、乙基甲基酮等，但在这样的液体中会膨胀。本文研究了苯乙烯与二乙烯基衍生物共聚物的分子尺寸分布。二乙烯基苯很难以纯单体状态获得和保存
Experiments on the influence of divinylbenzene on the polymerization of styrene were carried out sex'eral years ago by Staudinger ct al.(4,) and simi-lar studies were recently published by C’h. XYalling (7). The principal result is that copolymers containing only a few per cent of the cross-linking agent are insoluble in benzene, toluene, ethyl methyl ketone, etc., but do swell in such liquids. The purpose of this article is to investigate the molecular-size dis-tribution of copolymers of styrene and divinvl derivatives. Divinylbenzene is difficult to obtain andpreserve in the pure monomer state
