聚合松香的溴化及其生成物阻燃性的研究

Brominating of the Polyrosin and the Research of the Fire-Retardant Properties

研究了聚合松香与液溴反应生成溴化聚合松香的方法 ,测定了溴化聚合松香的红外光谱和差热分析曲线。溴化聚合松香本身不燃烧 。

Polyrosin reacts with bromine to produce the brominated polyrosin. This is an addition reaction accompanied with the substitution reaction. Brominated polyrosin was easy to eliminate the hydrobromic acid. We have determined the brominated polyrosin infrared spectroscopy and differential thermal curve. Brominated polyrosin does not burn itself. With bromintaed polyrosin, a coating can be made with fire retardant properties.
