The various proposed structures for polymers derived from benzyl type compounds have been discussed and the likelihood of these structures considered in the light of a study of their preparation and properties. Both the para substituted structure of Shriner and Berger and the pendant structure of Henne and Leicester were rejected chiefly on the basis of physical properties, degradation behavior, and
已经讨论了衍生自苄基型化合物的聚合物的各种建议结构,并根据对其制备和性质的研究考虑了这些结构的可能性。Shriner 和 Berger 的对位取代结构以及 Henne 和 Leicester 的悬垂结构都被拒绝,主要是基于物理特性、降解行为以及 X 射线和红外证据。Flory 的随机分支结构也无法解释降解行为和红外光谱。一种新的构型是非随机取代的、高度支化的分子。该结构主要包含两种类型的苯环,即,
