石油树脂的溴化及其生成物性能的研究

THE RESEARCH ON THE BROMINATIONOF PETROLEUM RESIN ANDITS DERIVANT PROPERTY

采用低温高浓度溴化加成法对Ｃ５－石油树脂进行了改性，其淡化产物在相对分子质量、玻璃化转变温度以及阻燃性等方面均有一定的提高。拓宽了石油树脂的应用范围。

In this paper, the bromination of PR is proceeded at the condition of high bromine con-tent and low temperature. The properties of the moleculer mass, glass transition tempera-ture and flame-resistant for modified product are increased in certain degree , which enlargesthe PR applied field in industry.
