    摘要: Poly(aryloxyphosphazene) copolymers are prepared having randomly repeating units represented by the formula: ##STR1## wherein R and R.sup.1 may be the same or different and are selected from the group consisting of monovalent aryl radicals and substituted aryl radicals having the structure: ##STR2## wherein X is a substituent selected from the group consisting of alkyl, alkoxy, aryl, aryloxy, amino and halogen substituted on any sterically permissible position on the phenyl group; and wherein the amount of Cl present in the form of P--C1 bonds is from about 0.4 percent to about 10 percent by weight based upon the total weight of copolymer.The copolymers may contain minor proportions of randomly distributed units in addition to the repeating units described above, these additional units containing reactive sites enabling the properties of the copolymers to be modified by crosslinking and/or curing.The copolymers are elastomeric even in the absence of low molecular weight polyphosphazene oils. The copolymers are curable by a variety of curing agents such as sulfur and peroxides, and can also be cured by radiation and ultraviolet light. The copolymers may be utilized in various applications such as foams and coatings, and are particularly suited for use in wire coating formulations.

    摘要: Linear polydihalophosphazene polymers which are substantially free of gel are prepared by thermally polymerizing a cyclic polyhalophosphazene represented by the formula (NPX.sub.2).sub.3, wherein X is fluorine, chlorine or bromine in the presence of a catalyst which comprises the reaction product of a boron trihalide compound with an oxygenated phosphorus compound.In addition to producing substantially gel free polymers, the catalyst composition of the process of the invention permits improved control of molecular weight, lower polymerization temperature, high rates of conversion of (NPCl.sub.2).sub.3 to (NPCl.sub.2).sub.n and provides for more readily processible and derivatizable polymers.

    摘要: The production of phosphazene polymers represented by the general formula ##STR1## WHEREIN R and R' are organic radicals hereinafter defined, and wherein n is an integer from 20 to upwards of 50,000 wherein one or more kinds of OR or OR' groups is attached to the phosphorus atoms in a substantially linear chain of alternating P and N atoms, the groups when more than one group is present being randomly distributed along the PN backbone, as described in copending United States Patent Application Ser. No. 824,004 filed Aug. 12, 1977, is enhanced by an improved procedure for the separation of the sodium chloride by-product from the derivatized phosphazene polymer. By treating the reaction mixture with carbon dioxide, in the presence of water and preferably with an additional alkali metal salt, agglomeration of the sodium chloride is accomplished, and a clean separation of the NaCl from the polyphosphazene ester is more readily achieved.

    摘要: The production of phosphazene polymers represented by the general formula ##STR1## WHEREIN N IS AN INTEGER FROM 7 TO UPWARDS OF 50,000 WHEREIN ONE OR MORE KINDS OF OR or OR' groups is attached to the phosphorus atoms in a substantially linear chain of alternating P and N atoms, the groups when more than one group is present being randomly distributed along the PN backbone, is enhanced by employing a single solvent for both each of the reactants (polydihalophosphazene and either aryloxide and/or alkoxide) and for the product (phosphazene polymer). By this expedient, the formation of the desired product is achieved in a homogeneous system rather than in a heterogeneous system as in the prior art where different solvents were employed for each of the reactants and for the reaction products.
