Abstract
Pyrolytic degradation of linear and crosslinked polystyrene
has been studied by analysis of the volatile degradation products
by mass spectrometry. The gas fraction V 300 c was analyzed
immediatly after pyrolysis or 24 hours later. Resulting degradation
products are formed in primary pyrolytic process and secondary
reactions. The content of divinylbenzene in the copolymer was
related to the quotient k which represents the ratio of light to
heavy components in the fraction V 300 c .
