Polycondensates and polymerizates made from hydrolyzable and polymerizable silanes

摘要: The invention includes hydrolyzable and polymerizable silanes, methods of making them using to obtain silicic acid(hetero)polycondensates acid(hetero)polymerizates. silanes have the formula I, ##STR1## wherein A=O, S, NH or C(O)O; B=a straight chain branched organic residue with at least one C═C double bond from 4 50 carbon atoms; R is an alkyl group, alkenyl aryl alkylaryl group arylalkyl group; R' a substituted unsubstituted alkylene arylene arylenealkylene alkylenearylene each having zero ten atoms, proviso that groups oxygen atom, sulfur atom and/or amine substituent; R1 represents nitrogen, alkylene, 1 10 said groups, substitutent; X hydrogen, halogen, hydroxy alkoxy acyloxy alkylcarbonyl alkoxycarbonyl --NR"2 ; R" H, aryl; Z=CO CHR4, R4 alkyl, alkylaryl; a=1, 2 3; b=0, 2; a+b necessarily=3; c=1, 2, 3 4; d=0 1.
