主权项

1. A hybrid polymer material, characterized in that it is provided in the form of a film and in that it results from the sol-gel polymerization by nucleophilic catalysis of at least one hybrid precursor of following formula (I): in which:
R1 and R3 are identical and represent a methyloxy or ethyloxy radical;R2 represents a methyl, ethyl, methyloxy, ethyloxy or phenyl radical;m is an integer varying from 2 to 6 inclusive;n is an integer equal to 1 or 2;and of at least one plasticizing precursor of following formula (II): in which:
R4, R′4, R6 and R′6 are identical and represent a methyl or ethyl radical;R5 and R′5, which are identical or different, represent a methyl, ethyl, methyloxy, ethyloxy or phenyl radical;x and x′, and y and y′, which are identical or different, are integers varying from 2 to 6 inclusive;z is an integer varying from 8 to 16 inclusive.
