1413780 Poly(aryloxyphosphazenes) HORIZONS RESEARCH Inc 10 June 1974 [11 June 1973] 25713/74 Heading C3R Poly(aryloxyphosphazene)polymers consist of randomly repeating units of formulµ where RSP1/SP and RSP2/SP are different aryl groups, RSP1/SP being phenyl, 3- or 4-substituted phenyl, 3,4- or 3,5-disubstituted phenyl or 3,4,5-trisubstituted phenyl, the substitutents being alkyl, alkoxy, phenyl, phenoxy, chlorine or bromine, provided there is not more than one halogen substituent, and RSP2/SP is a halogenated phenyl group of formula XC 6 H 4 -, X 2 C 6 H 3 -, 2,4,5-Cl 3 C 6 H 2 -, 2,3,4,6-Cl 4 C 6 H- or C 6 Cl 5 - where X is Cl or Br provided Br is present only in the 3-, 4- or 5- position. There may be from 20 to 50,000 units in the chain and the ratio of RSP1/SP to RSP2/SP groups may be from 95 : 5 to 5 : 95. The polymers are obtained by reacting poly(dichlorophosphazenes) first with one aryloxide salt and then with another aryloxide salt or by reacting with a mixture of aryloxide salts. Examples are given. Uses.-Films, fibres and shaped articles with flame-retardant properties.
