| 中文摘要 | three different heteroaromatic ring derivatives (coagents) were used to adjust the melt radical reaction of polypropylene (pp). from the results of high temperature h-1 nmr and high-temperature size-exclusion chromatography (ht-sec), all the coagents could quickly convert the tertiary pp macroradicals into resonance stabilized macroradicals and effectively restrain the beta-scission of pp macroradicals. long chain branched structures, without significant bimodal distribution of molecular weight, could be introduced into coagents-functionalized pp samples. effect of chemical structures of heteroaromatic rings and electron-attracting groups on the molecular structures and melt properties of modified pp samples was studied. the possible reactions of coagents-functionalized pp samples in different theoretical molar ratio of coagent to alkoxy radical were also proposed according to the results of h-1 nmr, torque curves, rheological measurements and ht-sec coupled with laser light scattering detector.
