Document Type and Number:
WIPO Patent Application WO/2022/138541
Kind Code:
A1
Abstract:
A polymetalloxane which comprises structural units represented by general formula (1-1) and general formula (1-2), while having a weight average molecular weight of from 30,000 to 2,000,000.
In general formula (1-1) and general formula (1-2), M1 and M2 represent different metal atoms that are 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; each of L1 and L2 independently represents a group that is selected from the group consisting of an allyloxy group, an aryloxy group and a trialkyl siloxy group; L1 and L2 may be the same or different, and at least one of the moieties represents an allyloxy group or an aryloxy group; each of R1 and R2 independently represents a hydrogen atom, an alkyl group having from 1 to 12 carbon atoms, or a group having a metalloxane bond; m represents an integer that shows the valence of the metal atom M1, while a represents an integer from 1 to (m – 2); and n represents an integer that shows the valence of the metal atom M2, while b represents an integer from 1 to (n – 2). The present invention provides: a metal atom-containing compound which is obtained by having a relatively low-cost compound react with a metal alkoxide, and which is stably present in the form of a transparent and uniform solution in an organic solvent, and is able to be present in the form of a transparent and uniform solution in the organic solvent without aggregating or gelling even if subjected to the action of hydrolysis or the like; a hydrolysis product of this metal atom-containing compound; and a polymetalloxane solution which has a high molecular weight, while making a stable polycondensation possible.
