Abstract
Abstract Polymeric materials represented by the general structure ##STR1## WHERE Q is a polymeric setment of ethylenically unsaturated monomers, lacking Zerewitinoff hydrogen atoms; X is the residue of a chain transfer agent; Y is the residue of a di-, tri, or tetraisocyanate radical after removal of isocyanage groups; A is the residue of a mercapto-, hydroxy-, or aminoalkyl alkoxy silane radical; and m and n are 1, 2 or 3, (the total not exceeding 4), Are useful as pigment dispersing aids in coating compositions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A polymeric material represented by the structure ##STR17## where Q is a non-resinous polymeric or copolymeric segment of a. an ester of acrylic acid or methacrylic acid with an alkanol of 1-18 carbon atoms; b. styrene or acrylonitrile; c. a vinyl ester whose ester moiety contains 2-18 carbon atoms; or d. a vinyl ether; X is the residue of a chain transfer agent; Y is the residue of a di-, tri-, or tetraisocyanate radical after removal of isocyanate groups; A is the residue of a mercapto-, hydroxy- or aminoalkyl alkoxy silane radical; and m and n are 1, 2 or 3, the total not exceeding 4, provided that when n is 2 or 3, only one of A need be as defined
