| 中文摘要 | the radiation-induced chain-scission and racemization of isotactic poly(methylmethacrylate)(iso-pmma) in amorphous and semi-crystalline state as well as in solution have been studied with nuclear magnetic resonance and molar mass deter-mination. it is shown that the chain-scission is dominant for iso-pmma in dilute solution while the racemization reaction is not favorable in this case. on the contrary, the racemization is favorable when iso-pmma was irradiated in its crystalline state while chain-scission is not. such experimental results could be well explained by the mobility of molecules and "cage effect". the hypothesis, we proposed previously that the chain-scission, racemization and recombination are in competition and the final result depends on the state of molecular motion at which iso-pmma was irradiated, has been verified verified once again. |
