The title compound (PTCMA) was irradiated in O2-free dioxane solution by 6ยฐCo-7-rays or by 100nsec-pulses of 16 MeV electrons. At concentrations below ca 0.04 base mol/l, main-chain scission occurred as was concluded from the decrease of the light scattering intensity (LSI). G(S) -3.7 \_+ 0.4 was in
Poly-ct-methylstyrene (PctMS) was degraded in CHCI 3 and CC14 solution by flash photolysis (2 = 265 nm). The degradation, as detected by light scattering measurements, is caused by the attack on PctMS by solvent radicals, assumed to be formed mainly by energy transfer processes. The direct effect di
Polyisobutene (PIB) dissolved in saturated hydrocarbons was degraded by irradiation with 2 ,us impulses of 15 MeV electrons. The time dependence of the change of light-scattering intensity (LSI) (due to the decrease of molecular weight) was measured. The half life r I,\_,(LS) of the decrease of LSI
