摘要 大分子改性剂是多种单体聚合成的产物,具有结构多样、官能团种类多的特征,应用领域广。以二甲苯为溶剂,γ-(甲基丙烯酰氧基)丙基三甲氧基硅烷(MAPTMS)和苯乙烯(St)为单体,以过氧化二苯甲酰(BPO)为引发剂,十二烷基硫醇(DMP)为链转移剂,通过两步自由基聚合法合成大分子改性剂。通过傅里叶变换红外光谱、核磁共振氢谱、热失重分析、差示扫描量热法对产物进行了分析,并经过核磁共振氢谱计算出相对分子质量。热分析表明产物具有良好的热稳定性,适用于橡塑体系的改性。

Abstract: Macromolecular modifiers are the products from polymerization of various monomers,which has a variety of structure and functional groups and wide application field.The macromolecular modifiers were successfully synthesized via two-step free radical polymerization with γ-methacryloxypropyl trimethoxysilane (MAPTMS) and styrene (St) as monomers,dibenzoyl peroxide (BPO) as initiator and dodecyl mercaptan (DMP) as chain transfer agent in dimethylbenzene.The products were analyzed by infrared spectroscopy (FT-IR),nuclear magnetic resonance spectroscopy (1H-NMR),thermogravimetric analysis (TG) and differential scanning calorimetry (DSC).The molecular weight was calculated by H-NMR.Thermal analysis showed that the products had good thermal stability,and which was suitable used for the modification of rubber and plastics.
Key words:  two-step radical polymerization    macromolecular modifier    active polymerization    polymer
