Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to compositions for dissolving polymetalloxanes. Polymetalloxane has, for example, the general formula Yl (wherein M 1 is a metal of 4 and M2 is a metal of am).

Yl and Yz are one unit having the structural unit of
It is widely used as an adhesive and other agents. Polymetalloxane is made of metals such as 1 and 3, but 1 and 2 are alkyl groups and alkyl groups. It has the property that hydroxyl groups can easily enter it. Polymetalloxane is a common organic solvent,
For example, aliphatic swelling hydrogens such as hep-I and hexane.

Diethyl ether etc. tII&/II! 1, and such organic solvents are generally used. However, when the above-mentioned known organic [1'Cjl-decomposed polymetalloxanes] come into contact with air or water, the lI chain position is replaced by a hydroxyl group, and as the hydroxyl group content increases, it gels and its solubility in W mechanism decreases. In addition, polymetalloxane is often used in a highly concentrated form, but in this case, due to its low solubility in lI#, production of metalloxane is difficult. Adheres to transport, storage, and toilet equipment.

This has disadvantages such as making it extremely difficult to remove the husband. The present inventors have carried out extensive research in order to find an organic composition that does not cause the above-mentioned disadvantages, that is, can dissolve or make latent gel or -type polymetalloxane.
