嵌段共聚物

Block copolymers have rich phase behavior,and in the bulk they can microphase-separate to form spheral,cylindrical,bi-continuous or layered structure.

A series of tri-block copolymers of styrene/tetradecyl methyl acrylate/3-methacryloxyl-propyl thimethoxyl silane was synthesized by atom transfer radical polymerization. The structures of those copolymers were characterized by means of gel permeation chromatography, infrared spectrum, and nuclear magnetic resonance (1H-NMR). Effect of tri-block copolymers on the mechanical properties of glass fiber/polypropylene composites was also investigated.
