1. A polymer containing repeating units of the formula:

  • ##STR25## wherein;

    each Y is --O-- or --NR30 -- wherein R30 is H or C1 -C6 alkyl;

    each R1, R2, R3, R4 and R5 is independently selected from the group consisting of H, C1 -C6 alkyl, C1 -C6 haloalkyl, C2 -C6 alkyl wherein at least one methylene group is replaced with --O--, C2 -C6 haloalkyl wherein at least one methylene group is replaced with --O--, and --RSi ;

    m and n are independently 0 or an integer of 1 to 6;

    each RSi is independently an organosilicon radical; and

    R is the divalent residue of an α



    -dihydroxyl compound or an α



    -diamino compound.
