Abstract
Mass spectrometric quantitative analysis on the gaseous and volatile products formed by yrolysis of polyvinyl alcohol and polyvinyl chloride in a vessel containing the calibrated amounts of air at various temperatures was studied. The pyrolytic products were hydrogen, carbon monoxide, carbon dioxide, lower hydrocarbons and others. Similar experiments were also carried out for the synthetic fibers, and the main components of the gaseous and volatile products formed by pyrolysis were identified. No marked difference in the composition and amounts of the gaseous and volatile products at each pyrolytic temperature between polyvinyl chloride and polyvinyl chloride fiber was observed.
