Abstract:
A polycondensate or heteropolycondensate, based on hydrolytically condensable monomer compounds of silicon, comprising from 5 to 100 mole percent, based on monomer content, of at least one hydrolytically condensable monomer compound selected from the group consisting of silanes of the formula I,B{A-(Z).sub.d -R.sup.1 (R.sup.2)--R'--SiX.sub.a R.sub.b }.sub.c(I),wherein a=1, 2 or 3 and b=0, 1 or 2;with the proviso that a+b=3;and c=1, 2, 3 or4;wherein B=a straight chain or branched chain organic residue having at least one C.dbd.C double bond and having 4 to 50 carbon atoms;X represents a member selected from the group consisting of hydrogen, halogen, hydroxy groups, alkoxy groups, acyloxy groups, alkylcarbonyl groups, alkoxycarbonyl groups and --NR"".sub.2 ;R"" represents a member selected from the group consisting of hydrogen, alkyl groups and aryl groups;R represents a member selected from the group consisting of alkyl groups, alkenyl groups, aryl groups, alkylaryl groups and arylalkyl groups;R' represents a member selected from the group consisting of substituted and unsubstituted alkylene groups, arylene groups, arylenealkylene groups and alkylenearylene groups each having zero to ten carbon atoms, wherein said substituted alkylene groups, said substituted arylene groups, said substituted arylenealkylene groups and said substituted alkylenearylene groups each have at least one substituent selected from the group consisting of oxygen atoms, sulfur atoms and amine groups;R.sup.1 is a member of the group consisting of nitrogen, substituted and unsubstituted alkylene, arylene and alkylenearylene groups each having from 1 to 10 carbon atoms, wherein said substituted alkylene groups, said substituted arylene groups and said substituted alkylenearylene groups each having from 1 to 10 carbon atoms each have at least one substituent selected from the group consisting of oxygen atoms, sulfur atoms and amine groups;R.sup.2 is a member selected from the group consisting of H, OH and COOH; andwherein, when said d=1, Z=CO, said R.sup.1 is one of said substituted and unsubstituted alkylene groups, said arylene groups and said alkylenearylene groups each having from 1 to 10 carbon atoms and said R.sup.2 is one of said H and said COOH, then A represents a member selected from the group consisting of an oxygen atom, a sulfur atom and an NH group;wherein, when said d=1, Z=CHW and W represents a member selected from the group consisting of H, alkyl groups, aryl groups and alkyaryl groups, said R.sup.1 is one of said substituted and unsubstituted alkylene groups, said arylene groups and said alkylenearylene groups each having from 1 to 10 carbon atoms and said R.sup.2 is said OH, then A represents a member selected from the group consisting of an oxygen atom, a sulfur atom, an NH group and a COO group;wherein, when said d=0 and said R.sup.1 is one of said substituted and unsubstituted alkylene groups, arylene groups and alkylenearylene groups having from 1 to 10 carbon atoms and said R.sup.2 is said OH, then A represents a member selected from the group consisting of an oxygen atom, a sulfur atom, an NH group and a COO group; andwherein, when said d=1, Z=CO, said R.sup.1 is said nitrogen and said R.sup.2 =said H, then A is S.
