The inducement of contacting media and rejection of crystallization of polyolefins leading to the aggregation of macromolecular surface modifiers on the surface of polymers were studied.

The hydrophilicity of polypropylene surface can be obviously improved by blending the polypropylene with a macromolecular surface modifier graft copolymer of methacrylic acid and random polypropylene (APP-g-MAA) and a graft copolymer of methacrylic acid and polypropylene wax (PPw-g-MAA),respectively.

A self-made macromolecular surface modifier acrylate-methyl methacrylate-vinyl triethoxy silane(BA-MMA-VTES)was used for surface modification of nano-sized Silicon Nitride(Si3N4) ceramic power and the modified nano-Si3N4 powder was added to hydrolysis-resistance polyurethane(PU) leather.

Tricopolymer macromolecular modifier, MAA-BA-AN,was synthesized by radical polymerization from methacrylic acid(MAA),butyl acrylate(BA) and acrylic nitrile(AN).

In this work,a new macromolecular modifier butyl acrylate-methyl methacrylate-vinyltriethoxysilane(BA-MMA-VTES tercopolymer)was synthesized via radical polymerization under optimum conditions adopting BPO and DCP as initiators.

The development and the essential assortment of the surface modifying macromolecules(SMM) were general summarized and the fundamental principles about the design and synthesis of the surface modifying macromolecules were discussed.

Synthesis and characterization of titanate macromolecular surface modifier

With the measurement of mechanical properties and analysis of SEM, effects of selfmade macromolecule interfacial modifier on the mechanical properties of PA6/brucite composites were studied, and they were compared with those of coupling agent TC-114.
