Thermal degradation of hydrogenated hydroxy terminated polybutadiene (HHTPB) and copolyurethanes based on HHTPB and HTPB with varying compositions of HHTPB were studied by thermogravimetric and pyrolysis-g.c, techniques. HHTPB was found to decompose in two stages and the kinetic parameters as evalua

The mechanism of the thermal degradation of polystyrene was studied by pyrolysis-gas chromatography and pyrolysis-field ionization mass spectrometry, using a block copolymer of ordinary and perdeuterated styrene [poly(styrene-b-styrene-ds) ]. The main degradation products were monomers, dimers and t
## Abstract The thermal degradation of aromatic polyimides in nitrogen at 700Β°C was studied using pyrolysis gas chromatography, infrared spectroscopy, and radiochemical techniques. Degradation mechanisms were postulated to account for the breakdown products found and to explain variations in the ra
Pyrolysis gas chromatographic investigations have been carried out on copolymers of styrene with trimethyl-vinyl-silane and of styrene with dimethyl-phenyl-vinyl-silane, in order to study the mechansims of thermal degradation and the copolymer structures. We have identified the pyrolysis products an
