摘要: 液溴与聚-4-甲基-1-戊烯（PMP）的四氯化碳溶液反应，在光照条件下得到溴代PMP，通过红外与元素分析确证了其结构。并通过热重分析对其性能进行了初步的研究。研究发现，在光照条件下溴原子很容易与PMP中叔丁基上的氢原子发生取代反应，得到化学掺杂溴原子的聚合物。该聚合物在150℃以下比较稳定，在150℃以上就会失去HBr。采用此种方法，可得到掺杂均匀的低密度材料。

Abstract: This paper presents the preparation of patially brominated poly-4-methyl-1-pentene(PMP).The composition and stucture of patially brominated PMP are studied by means of element analysis，IR and TGA. Br atom was found to be substituated easily with H atom of PMP to form the chemical doped polymers．The polymer will be stabilized below 150℃and lose the HBr up to 150℃. The well doped low density material was made by this means.-
