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.
