Study on the Melt Grafting Synthesis of Polypropylene-g-Glycidyl Methacrylate
Gao Guo-sheng · Journal of Jiangsu Polytechnic University · 2003
The melt grafting of glycidyl methacrylate(GMA) onto polypropylene in a co-rotating twin screw extruder was studied.The influences of different factors such as reaction time,concentration of monomer and initiator on grafting reaction were explored.Grafting yields of GMA with high grafting degree and good flowing and gloss properties were obtained through the control of experimental conditions.GMA was high boiling and low toxic as monomer grafting on polypropylene molecular,it could improve polypropylene compatibility with polyimide polyester and so on,it could improve polypropylene coating adhere property.
