摘要：

Polystyrene (PS) and poly-alpha-methylstyrene (PMS) in various kinds of solvents such as 1-methylnaphthalene, tetralin and phenol were thermally degraded in the temperature range from 250 to 450-degrees-C. The conversion of PS to low molecular weight products depended on the kinds of solvents and the polymer concentration, whereas the conversion of PMS was independent of both of these. The difference in degradation behaviour between the polymers was explained in terms of a mechanism which involves hydrogen transfer steps from solvents to intermediate polymer radicals.
