紫胶的改性研究

Research of modifying of the lac

以紫胶为原料,高锰酸钾为引发剂,接枝甲基丙烯酸甲酯(MMA)制取接枝共聚物,对最佳反应条件进行研究.结果表明:接枝率越大越好,改性后的紫胶在韧性、耐水性等方面,比原紫胶具有很大的优越性.

The graft-copolymerizated agents was prepared from lac and MMA with potassium-permanganate as iritiator.The results show that lac modified has better water-tolerant characteristic and toughness than the lac.
