Suitable polyphosphazene derivatives containing carbonyl groups for photocrosslinking processes.

摘要

Polyphosphazene derivatives containing carbonyl groups apt to undergo rapid photoreticulation processes having the general formula CHEM in which: X represents substituents bound to the polyphosphazene chains by means of hydroxy or amino functions, and containing carbonyl groups; X min represents additional substituents bound to the polyphosphazene chain through hydroxy or amino functions and containing one or more easily extractable hydrogen atoms; (w + y + z) is an integer between 20 and 15.000; w z are integers higher than or equal to 0 and always lower than 15.000; y is an integer between 20 and 15.000. n
