β¦ Synopsis
The products of the thermal decomposition of a series of copolymers of structure
Ph
Ph A with n = 0, I, 3, 4 and 5, have been investigated. A high proportion of the products consists of low molecular weight analogues of the parent polymers, with styrene the major constituent of the volatile liquids. The eopolymers are more stable than head-to-tail polystyrene. Some general conclusions are drawn on the overall mechanism of breakdown.

Copolymers of 1,2,2,2-tetrachloroethyl esters of unsaturated acids and halogenated N-phenyl maleimides with styrene were pyrolyzed; volatile products were analyzed with a mass spectrometer combined with a gas chromatograph. Hydrogen halide and carbon dioxide in the volatile products were determined
The product and kinetic analyses of the thermal decomposition of head-to-bead poly-amethyl styrene are investigated. From the results, a mechanism of breakdown is postulated.
The mechanism of silane thermal decomposition is investigated in a flow reactor. The time dependencies of silane consumption and disilane formation were compared with those parameters of solid product (aerosol particles) such as concentration, total hydrogen content in solid product, and fraction of
