Classification: CPC C | IPC C

Claim 0:
1. A polymer comprising:
a reactive silicon group represented by General Formula (1):

—Si(R1)3-a(X)a  (1)

wherein:
each R1 is independently a hydrocarbon group having 1 to 20 carbon atoms, wherein the hydrocarbon group of R1 is optionally substituted with a hetero-containing group as a substituent,
X is a hydroxyl group or a hydrolyzable group,
a is 1, 2, or 3, and
an atom adjacent to the reactive silicon group has an unsaturated bond; and
a polyoxyalkylene main chain backbone selected from the group consisting of polyoxyethylene, polyoxypropylene, polyoxybutylene, polyoxytetramethylene, a polyoxyethylene-polyoxypropylene copolymer, and a polyoxypropylene-polyoxybutylene copolymer,
the polymer has at least one structure selected from the group consisting of the structures represented by General Formulas (2) to (4):, R4 is a divalent linking group, wherein each of two bonds that R4 has is bonded to a carbon atom, an oxygen atom, a nitrogen atom, or a sulfur atom in the linking group,
R2 and R3 are each independently selected from a hydrogen, an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, or a silyl group, and
R1, X, and a are as described above.
