Hybrid-functional polymers

摘要

Hybrid-functional polymer (Q), is new. Hybrid-functional polymer (Q) of formula (R-(Z 0>-O-CH 2-C(Y 1>)(L 1>-(Z 1>) k)-O-C(=O)-NH-Y 0>-(NCO) v) n) (I) or (R-(Z 0>-O-CH 2-C(Y 1>)(L 1>-(Z 1>) k)-O-C(=O)-NH-Y 0>-(NH-C(=O)-X 0>) v) n) (II), is new. R : a n-valent polymer residue; Z 0>-CO-, -X-CO-R 2>-CO- or -X-CO-[X 1>] mA-; X : O, NR 4>or S; R 4>H or 1-10C-alkyl; X 1>NR 4>, CH 2or C 2H 4; m : 0 or 1; R 2>a dicarboxylic acid, after removing two carboxyl group, preferably an optionally saturated, optionally substituted 1-6C-alkylene, or optionally substituted phenylene group; A : optionally substituted arylene residue; Y 0>(v+1)-valent residue of polyisocyanate, after removing isocyanate group; Y 1>H or CH 3; Z 1>a functional group, which is different from NCO and is not reactive with isocyanate group; L 1>(k+1)-valent organic residue, with which the functional group (Z 1>) is connected with the residue of (I); X 0>a blockage group different from Z 1>, which is removed at a temperature of greater than 100[deg] C, or -X1a-L 1>-(Z 2>) k1; Z 2>a functional group, which is different from Z 1>and NCO, and is non-reactive with isocyanate group or less reactive than the HX1a; L 2>(k 1+1)-valent organic residue, with which the functional group (Z 2>) is connected with the residue of (II); X1a : O, NH, NR 3>or S; R 3>optionally saturated alkyl, optionally substituted aryl or alkaryl residue, or -L 2>-(Z 2>) k1; k, k1, v : 1-3; and n : 2-4. Independent claims are included for: (1) the preparations of (Q); (2) a composition comprising (I); (3) a process for the preparation of a coating, adhesive or sealant comprising mixing (I) with at least a further components and crosslinking the obtained product; and (4) a composite body obtained by adhering at least two substrates by the composition.
