Disclosed is a silyl group-containing polymer which can be cured quickly and firmly. This silyl group-containing polymer enables to obtain a cured product which exhibits excellent antifouling property and weather resistance, while maintaining good rubber elasticity. Also disclosed is a method for producing such a silyl group-containing polymer. Specifically disclosed is a silyl group-containing polymer represented by the following general formula (1). (1) [In the formula (1), R1 represents a remaining group obtained by removing all the hydroxyl groups from a monohydroxy or polyhydroxy compound having t hydroxyl groups in a molecule; R2 represents a divalent organic group; R3 represents an optionally substituted monovalent organic group having 1-20 carbon atoms; X represents a hydroxyl group or a hydrolyzable group; Y represents a divalent group represented by the general formula (A) below or a divalent group represented by the general formula (B) below; a represents an integer of 1-3; r represents an integer of 1-1000; and t represents an integer of 1-8. In this connection, when the silyl group-containing polymer represented by the general formula (1) has a plurality of Y's in a molecule, the Y's may be the same as or different from one another. When t is 2-8, a plurality of monovalent groups bonded to R1 may be the same as or different from one another. (A) (B) In the formula (A), R4 represents an alkylene group having 2-8 carbon atoms. In the formula (B), R5 represents an alkylene group having 2-4 carbon atoms. |
