【摘要】 根据红外分析、顺磁共振、光电子能谱及化学分析结果,我们提出了氟塑料—46的辐射交联反应机理。交联点不一定如Bowers等由理论分析推断的在氟塑料—46的—CF₃侧链上。我们认为可以由 CF₃链侧自由基如—CF₂—CF—CF₂—,—CF₂—C—CF₂—,直接复合成交联键,H型交联;或由链侧自由基和链端自由基复合通过支化而交联,即T型或Y型交联。后者机率更多些。更多还原

【Abstract】 On the basis of the results of IR analysis, ESR. ESCA and chemicalanalysis, we suggest the mechanism of radiation crosslinking of fluoropolymer Fs-46.The crosslinking point of Fs-46 is not on the side chain -CF₃-group. as Bowers sug-gest with their tbeoratical analysis; we find that they may carried out with recombina-tion of two side chain radicals directly, as, -CF₂-C-CF₂-, -CF₂-CF-CF₂-,crosslinking with H type, or recombination of side chain radicals and chain endradicals through branching and then crosslinking. It is crosslinking with T typeor Y type. The later one is the probable mechanism.更多还原
