| 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 kinetic studies on reactive extrusion have been carried out because of the inherent difficulties, as expected. in this work, we have studied chain propagation kinetics on melt grafting using pre-irradiated linear low density polyethylene (lldpe) and three monomers, acrylic acid (aa), methacrylic acid (maa), and methyl methacrylate (mma), as the model system. we measured the apparent chain propagation rate coefficients of grafting (k(p,g)) and homopolymerization (k(p,h)) at an initial stage for the melt grafting by ft-ir spectroscopy and electron spin resonance spectroscopy. it was observed that the convective mixing affected the rate coefficients. the magnitude of k(p,h) and k(p,g) were in the same order, but k(p,h) was slightly larger than k(p,g) the k(p,g) of the three grafting systems increased in the order: lldpe/mma < lldpe/maa < lldpe/aa. these results are explained in terms of phase separation, solubility, and inherent reactivity of the monomer. |
