Abstract
1355238 Curable fluorophosphazene polymers HORIZONS RESEARCH Inc 25 Oct 1971 49381/71 Heading C3R Fluorophosphazene polymers contain units of formulµ where Y is F(CF 2 ) n /CH 2 )O- or H(CF 2 ) n (CH 2 )O- and n is from 1 to 4, Z is F(CF 2 ) m (CH 2 )O- or H(CF 2 ) m (CH 2 )O- and m is from n+2 to n+5, the Y : Z ratio is from 1 : 3 to 3 : 1, W is a chlorine atom or a group capable of further reaction to cross-link the polymers and the ratio (Y+Z) : W is greater than 5 : 1. The polymers are prepared by reacting alkali metal fluoroalkoxides-with polymers of phosphonitrilic chloride, the reactive groups being introduced at the same time or subsequently. In examples phosphonitrilic chloride polymer is reacted with sodium alkoxides of trifluoroethanol, heptafluorobutanol, 2 - methyl - 2 - propene - 1 - ol, octafluoropentanol, allyl alcohol and trifluoropropene-1-ol, the resulting products being crosslinked by reaction of the unsaturated groups in the presence of perioxides and by reaction of chlorine atoms; in other processes the phosphonitrilic polymer is partially hydrolysed to introduce hydroxyl groups, reacted with the sodium alkoxides of trifluoroethanol, heptafluorobutanol, tetrafluoropropanol, dodecafluoroheptanol and octafluoropentanol, to obtain polymers containing hydroxyl groups and fluorinated groups, these polymers being reacted with triethoxyphenyl silane, triethoxy silanol, diethoxy silane diol, dimethyl silanol and triacetoxy methyl silane to replace the hydroxyl groups by silicon-containing groups through which the polymers are cross-linked by reaction with diethoxy silane diol and diethyl silane diol and by exposure to moist air; also, phosphonitrilic chloride polymer is reacted with trifluoroethanol and heptafluorobutanol together with N-parahydroxyphenyl propionamide and with N-(3-hydroxy-n-propyl)- acetamide, the products being hydrolysed to obtain polymers with amino groups through which they may be cross-linked by reaction with phenyl diisocyanate and methyl ethylene-bis- (urethane)
