    • An improved process for the preparation of highly fluorinated phosphonitrilic elastomers is disclosed. The fluoroalkoxy substituents on phosphonitrilic fluoroelastomers which contain some or all fluoroalkoxy groups in which the terminal carbon bears one or more hydrogen atoms are exchanged with fully fluorinated alkoxide groups in which the terminal carbon bears three fluorines. The process is accomplished using a ligand replacement mixture of an alkali metal fluoroalkoxide of the formula MOC.sub.n.sup.f and a fluoroalcohol of the formula HOC.sub.n.sup.f' where C.sub.n.sup.f is --(CH.sub.2).sub.y (CF.sub.2).sub.n CF.sub.3 where y is an integer 1 or 2 and n is an integer from 0 to 20 and C.sub.n.sup.f' is the same or different from C.sub.n.sup.f where C.sub.n.sup.f' is --(CH.sub.2).sub.y (CF.sub.2).sub.n CF.sub.3 where y and n are as previously defined.
    • 公开了制备高度氟化的膦腈基弹性体的改进方法。 含有末端碳带有一个或多个氢原子的一部分或全部氟代烷氧基的磷腈基含氟弹性体上的氟代烷氧基取代基与其中末端碳带有三个氟的完全氟化的醇盐基团交换。 该方法使用式MOCnf的碱金属氟代烷氧化物和式HOCnf'的氟代醇(其中C nf是 - (CH 2)y(CF 2)n CF 3)的配体置换混合物完成,其中y是整数1或2,并且n是 Cnf'与Cnf相同或不同,其中Cnf'是 - (CH2)y(CF2)nCF3,其中y和n如前所定义。

    • A process for treating the surface of a cured phosphonitrilic fluoroelastomer of the formula ##STR1## where x is an integer of from about 3 to about 50,000, Q and Q' are the same or different and are fluoroalkoxy of the formula --OCH.sub.2 (CF.sub.2).sub.m CF.sub.2 Z where m is an integer from 0 to 20 and Z is hydrogen or fluorine and Q" is a group having some olefinic unsaturation with a solution of an alkali metal fluoroalkoxide of the formula MOC.sub.n.sup.f where M is an alkali metal and C.sub.n.sup.f is a fluorocarbon moiety of the formula --(CH.sub.2).sub.y (CF.sub.2).sub.n CF.sub.3 where y is 1 or 2 and n is an integer from 1 to 20. The process of this invention causes the replacement of some of the Q and Q' groups with --OC.sub.n.sup.f. The decreased number of Q and Q' where Z is hydrogen results in a cured phosphonitrilic fluoroelastomer surface displaying improved resistance to polar solvents.

    • The fire retardancy of polyesters is enhanced with halophenoxyphosphazenes that contain a P--O--P bond. Preferred materials are reaction products of a halogenated phenol and a phosphonitrilic halide. Brominated phenols are preferred although chlorophenols can be used. Of the brominated phenols, preferred starting materials are p-bromophenol, 2,4-dibromophenol and mixtures thereof. Phosphonitrilic chlorides are preferred starting materials. Pure phosphonitrilic halides can be used; however, phosphonitrilic halide mixtures are preferred because of their availability. Cyclic and linear phosphonitrilic halides are useful as well as mixtures thereof. Saturated and unsaturated polyesters can be made fire retardant by this invention, as can thermoplastic and thermosetting materials. Linear and crosslinked polyesters can be treated. Preferred polyesters are fiber-forming polyesters of a diol and dibasic acid, such as poly(ethylene terephthalate) and poly(1,4-cyclohexylenedimethyleneterephthalate).
