MALEIC-ANHYDRIDE GRAFTING ON EPDM RUBBER IN THE MELT

[摘要] The grafting of maleic anhydride on a EPDM rubber was studied with a twin screw extruder. The effect of barrel temperatures,throughput, maleic anhydride concentration and peroxide concentration [bis(t-butyl peroxy isopropyl)benzene] on the degree of grafting and melt viscosity was studied. The maleic anhydride concentration was determined by potentiometric titration and a correlation was made with quantitative i.r. analysis.
