Abstract

The decrease of polyene concentration and the elimination of hydrogen chloride have been studied in the oxidation of thermally predegraded PVC powder samples. The rate of both processes increases with increasing predegradation time and oxygen pressure. The close correlation between the thermooxidative hydrogen chloride elimination and polyene oxidation has been shown.

Abstract

Пониже концентрации полиенов и скорости выделения соляной кислоты было изучено в процессе окисления порошков ПВХ, подвергнутых предварительной термодеградации. Скорость обоих процессов увеличивается с увеличением времени предварительной обработки и давления кнслорода. Была обнаружена близкая корреляция между термоокислительным быделением HC1 и окислением полиенов.
