A water-soluble silicon-containing polymer is provided comprising recurring units having formula (1) wherein 10 ≤ m ≤ 260, 1 ≤ n ≤ 100, X is an alkylene chain which may have an alkyl substituent, R is H, alkyl or acetyl, and "a" = 1, 2 or 3. The polymer has more than one primary amino group per hydrolyzable silyl group, affording an increased number of reaction sites with organic resins and forming a firm bond therewith. |
