iene-1,3 polymerized very rapidly and yielded a rubber-like polymer, which alter vulcanization was less extensible than the corresponding product obtained from chloroprene (chloro-2-butadiene-1,3). Chloro-2-dimethyl-3,4-butadiene-1,3 polymerized very slowly and the product, even alter vulcanization, was soft and lacking in nerve. Chloro-2-tetramethylene-3,4-butadiene-1,3 also polymerized very slowly
摘要 三种取代的乙烯基乙炔用氯化氢处理,转化为相应的氯丁二烯。Chloro-2-methyl-3-butadiene-1,3 非常迅速地聚合并产生橡胶状聚合物,其硫化后的延展性低于从氯丁二烯 (chloro-2-butadiene-1,3) 获得的相应产品。Chloro-2-dimethyl-3,4-butadiene-1,3 聚合非常缓慢,产品即使在硫化后也很柔软,缺乏神经。Chloro-2-tetramethylene-3,4-butadiene-1,3 也非常缓慢地聚合并且产物非常柔软、可塑性和粘性。这三种新的氯丁二烯的结构是通过它们与 α-萘醌反应形成结晶加成产物而建立的,这些加成产物被氧化成相应的蒽醌。
