| titleOfInvention | Production of polyphosphazene |
| abstract | PURPOSE: To obtain easily a polyphosphazene having useful characteristics in the fields of medical treatment, electrical components, chemical industry, etc., according to the type of substituents, by reacting a specified polyphosphazene with a Grignard compd. in a solvent. n CONSTITUTION: A polydichlorophosphazene (a) is reacted with an alkoxide compd. (b) to obtain a stable polyphosphazene (A) mainly composed of repeating units of formula I [wherein R 1 and R 2 are each an aliph. group such as a (halogen-substd.) 1W10C linear satd. hydrocarbon group]. The component A is reacted with a Grignard compd. (B) of formula II [wherein R 3 in a (substd.) aliph. group; and X is halogen] in a solvent consisting of an aprotic polar solvent (c) such as tetrahydrofuran and an aprotic non-polar solvent (d) such as benzene in a ratio of (c) to (d) of 0W10 by volume to substitute at least part of OR 1 and/or OR 2 groups of the component A by R 3 group(s) of the component B, thus obtaining a polyphosphazene. n COPYRIGHT: (C)1988,JPO&Japio |
