| 摘 要： | A tri-block copolymer coupling agent polystyreneblock-poly （n-butyl-acrylate）-block-poly （y-methacryloxypro pylt rimethoxysilane）（PS-b-PnBA-b-PMPS） was synthesized by atom transfer radical polymerization （ATRP）, and its molecular structure was characterized by fourier-transform infrared spectra, hydrogen nuclear magnetic resonance and gel permeation chromatography. The glass bead was treated with the block copolymer coupling agent, and then studied by transmission electron microscopy. The result showed that strong interaction was formed between the block copolymer coupling agent and the surface of glass bead, and then the block of poly（n-butylacrylate） formed a layer of film on the surface.

| Abstract: | A tri-block copolymer coupling agent polystyrene biock-poly(n-butyl-acrylate)-block-poly(r-methacryloxypro pylt rimethoxysilane)(PS-b-PnBA-b-PMPS)was synthesized by atom transfer radical polymerization(ATRP),and its molecular structure was characterized by fourier-transform infrared spectra,hydrogen nuclear magnetic resonance and gel permeation chromatography.The glass bead was treated with the block copolymer coupling agent,and then studied by transmission electron microscopy.The result showed that strong interaction was formed between the block copolymer coupling agent and the surface of glass bead,and then the block of poly(n-butylacrylate)formed a layer of film on the surface. |
