P. Carty et S. White, IRON-CHLORINE INTERACTIONS IN BLENDS OF POLY(VINYL CHLORIDE) AND ACRYLONITRILE-BUTADIENE-STYRENE CONTAINING BASIC IRON(III) OXIDE, Polymer, 36(5), 1995, pp. 1109-1111
A systematic study of char formation in blends of two thermoplastic po
lymers, poly(vinyl chloride) and acrylonitrile-butadiene-styrene, cont
aining a char-forming/smoke-suppressing iron compound, suggests that t
he 'active species' which promotes char-forming reactions in these pol
ymer systems is iron(III) oxychloride (FeOCl).
