摘要
本文用二甲苯为溶剂,有机过氧化物为引发剂,在135℃采用马来酸酐单体和聚丙烯的溶液接枝方法进行共聚,接枝物的红外吸收光谱,在1862cm^(-1)和1787cm^(-1)处,出现了特征吸收峰,证明其接枝物确系存在;同时发现马来酸酐单体的用量对接枝度有明显的影响,最后考察接枝物与高岭土共混,并着重对其抗张强度进行研究,得到满意的结果。
Polypropylene was graft polymerized with maleic anhydride at 135℃,with xylene as sol- vent and organic peroxide as initiator.The existence of graft copolymer was indicated by its infrared absorption spectrum.It shows a characteristic aborption peak at 1862cm^(-1)and 1787cm^(-1).The degree of grafting was found to be affected significantly by the amount of maleic anhydride monomer added. The polyblend of graft copolymer with kaolin was considered finally,with emphasis on its tensile strength.The results were satisfactory.
