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.
