The invention concerns a method for preparing by thermal activation of
hybrid silicone and organic polymers comprising the motifs
RxUySiO[4-(x+y)]/2 (I) wherein: x is equal to 0, 1, 2 or 3, y is equal to
0, 1, 2 or 3 with 2.ltoreq.(x+y).ltoreq.3 and y is different from 0 for at
least one of the hybrid copolymer motifs; and the symbols U, identical or
different, represent organic polymer units.
