Abstract:
A modified aluminum oxy compound, obtained by a process that comprises reacting:an aluminum oxy compound(a) having a ratio of an intensity at 30 ppm(H2) to an intensity at 10 ppm(H1)[H2/H1] in an 27Al-solid NMR spectrum of less than 0.35, water(b), and a compound(c) having a hydroxy group selected from the group consisting of tertiary alcohols and alcohols substituted with a halogen atom, the alcohols substituted with a halogen being selected from the group consisting of alcohols indicated by the formula CR1R2R3â€”OH (wherein each of R1, R2 and R3 independently represents a hydrogen atom or hydrocarbon group having 1 to 20 carbon atoms, which is optionally substituted with a halogen atom, and they may be mutually the same or different), halogenated phenol compounds and silanol compounds; wherein the modified aluminum oxy compound has a ratio of an intensity at 30 ppm(M2) to an intensity at 10 ppm(M1)[M2/M1] in an 27Al-solid NMR spectrum of 0.60 or more, the molar ratio[(a)/(b)] of the aluminum oxy compound(a) to water(b) is 1/3 to 1/0.01, and the molar ratio [(a)/(c)] of the aluminum oxy compound(a) to the compound(c) is 1/3 to 1/0.01.
