【摘要】 在氯丁橡胶中加入环化试剂AlEt2 Cl-C6H5CH2 Cl,在 12 0℃× 2 0min条件下 ,可制备环化氯丁橡胶。借助IR ,1H -NMR ,DSC ,GPC和裂解色谱测试方法对产物进行了表征。结果表明 ,二甲苯溶剂参与了环化反应 ,且随环化度增加 ,参与反应的溶剂二甲苯的数目也逐渐增加 ,并确定了环结构的形成更多还原

【Abstract】 The cyclized CR was prepared by adding in cyclic agent AlEt 2Cl-C 6H 5CH 2Cl at 120℃×20min.The products were characterized with the aid of IR, 1H-NMR,DSC,GPC and So on.The result indicated that xylene solution participated in cyclic reaction,and increased with the increase of the degress of cyclization,and the polycyclic structure was determined.更多还原
