Abstract

This research was carry out to evaluate the thermo-oxidative and photo-oxidative stability of industrially important vinyl polymers poly(methyl methacrylate) and polystyrene obtained by radical-initiated polymerization in the presence of some metal complexes. Under conditions characteristical of practical polymer operation, the thermal oxidative stability of PMMA obtained on ferrocene, titanocene dichloride and zirconocene dichloride increases by 27–49°C. PMMA and PS obtained by free-radical polymerization, and PMMA(FC), PMMA(TC), PMMA(ZC), PS(TC) may be characterized as relatively resistant to photo-ageing.

金属配合物存在下聚甲基丙烯酸甲酯和聚苯乙烯的热稳定性和光氧化稳定性

本研究对工业上重要的乙烯基聚合物聚（甲基丙烯酸甲酯）和聚苯乙烯在金属配合物存在下的热氧化和光氧化稳定性进行了评价。在实际聚合物操作条件下，在二茂铁、二茂钛和二氯化锆上制备的PMMA的热氧化稳定性提高了27 ~ 49℃。PMMA和PS通过自由基聚合得到，PMMA（FC）、PMMA（TC）、PMMA（ZC）、PS（TC）具有相对抗光老化的特点。

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
