Abstract

Chitin, a poly(saccharde) obtained from the shells of crustaceans, is the second most abundant naturally occurring biopolymer after cellulose. It is a copolymer of N-acetylglucosamine and N-glucosamine. Chitosan is derived from chitin by deacetylation. It, therefore, is a natural renewable resource and has many outstanding properties such as biocompatibility, biodegradability and nontoxicity. These properties make it an almost ideal base from which green phosphorus flame retardants may be developed. Treatment of chitosan with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide in carbon tetrachloride generates a phosphorus-containing polymer which displays a much reduced peak heat release rate upon combustion compared to that of unmodified chitosan. This material should function well as a flame-retarding additive for a number of polymers.
