摘要： A polymer including, as the main chain, a metal-oxygen-metal bond including a structural unit represented by the following general formula (1): wherein M represents a metal atom selected from the group consisting of Al, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Y, Zr, Nb, Mo, In, Sn, Sb, Hf, Ta, W, and Bi; R1 is selected from a hydrogen atom, a C1-C8 alkyl group, a C1-C8 alkylcarbonyl group, a C6-C12 aryl group, a C7-C13 aralkyl group, a (R53Si-group, a (R6R7N—) group, a 4-oxopent-2-en-2-yl group, a C5-C12 4-alkoxy-4-oxobuta-2-en-2-yl group, and a C10-C16 4-aryloxy-4-oxobuta-2-en-2-yl group; R2 and R3 are each independently a hydrogen atom or a C1-C8 alkyl group; R4 is a hydrogen atom, a C1-C8 alkyl group, or a C1-C8 alkylcarbonyl group; R5 is a hydroxy group, a C1-C8 alkyl group, a C5-C12 alicyclic alkyl group, a C1-C12 alkoxy group, a C6-C12 aryl group, a C7-C13 aralkyl group, or a group having a siloxane bond; a plurality of R5 may be the same or different; R6 and R7 are each independently a hydrogen atom, a C1-C8 alkyl group, a C5-C12 alicyclic alkyl group, a C6-C12 aryl group, a C7-C13 aralkyl group, or a C1-C12 acyl group; R6 and R7 may be linked via a carbon-carbon saturated bond or a carbon-carbon unsaturated bond to form a ring structure; m is an integer that represents the valence of the metal atom M; a is an integer of 1 to (m−2); and b is an integer of 1 to 6, and c is an integer of 1 to 5. Provided is a polymer including a metal-oxygen-metal bond as the main chain that is stably present without aggregating or turning into a gel even in high concentration and high viscosity.
