Abstract:
A (poly)oxyalkylene block silyl ester copolymer comprising silyl ester copolymer block units (A) and block units (B),said silyl ester copolymer block units (A) comprising: (a) component units derived from a polymerizable unsaturated carboxylic acid silyl ester, and (b) polymerizable unsaturated monomer units other than the component units (a), said block units (B) derived from a mercapto compound represented by the formula: wherein R1 represents a hydrocarbon group or ether-bond-containing hydrocarbon group having a valency of 1 or higher and having 1 to 30 carbon atoms; R2 represents a bivalent hydrocarbon group having 1 to 30 carbon atoms or a group of the formula â€”CH(R3)â€” wherein R3 represents a group of the formula R4â€”Oâ€”R5, R4 representing a bivalent hydrocarbon group having 1 to 30 carbon atoms, and R5 representing a monovalent hydrocarbon group having 1 to 30 carbon atoms; X represents: n is an integer of 1 to 5; m is an integer of 1 to 100; l is an integer of 1 to 5; k is an integer of 0 to 100; a is an integer of 0 or 1; j is an integer of 1 to 50; and i is the valency of R1.
