| 中文摘要 | graft copolymerization in the molten state is of fundamental importance as a probe of chemical modification and reactive compatibilization. however, few grafting kinetics studies on reactive extrusion were carried out for the difficulties as expected. in this work, the macromolecular peroxide-induced grafting of acrylic acid and methyl methacrylate onto linear low density polyethylene by reactive extrusion was chosen as the model system for the kinetics study; the samples were taken out from the barrel at five ports along screw axis and analyzed by ftir, h-1 nmr, and esr. for the first time, the time-evolution of reaction rate, the reaction order, and the activation energy of graft copolymerization and homopolymerization in the twin screw extruder were directly obtained. on the basis of these results, the general reaction mechanism was tentatively proposed. it was demonstrated that an amount of chain propagation free radicals could keep alive for several minutes even the peroxides completely decomposed and the addition of monomer to polymeric radicals was the rate-controlled step for the graft copolymerization. |
