Abstract

PURPOSE:To obtain a composition useful as a constituent element of polymerizable and curable coating compound or a new type combined function solvent, having excellent dissolving power and ability of initiation and promotion of radical polymerization, consisting of methoxyacetone and a peroxide. CONSTITUTION:For example, air is introduced to methoxyacetone at room temperature for 30-several hours to form about 0.1-2.0mol.% peroxide. When a radically polymerizable double bond-containing monomer, oligomeer or polymer is dissolved in the above composition or a solution of the polymerizable double bond-containing compound in methoxyacetone is brought into contact with oxygen, polymerization and curing are promoted. The composition is useful as a raw material for organic peroxides or a coating compound requiring no addition of polymerization initiator.

As a result of a more detailed study of the basic physical properties of methoxyacetone, it was found that methoxyacetone forms peroxides under mild conditions such as room temperature and air contact. For example, add methoxyacetone to room temperature for several minutes to several hours.
Preferably, just by blowing air for 30 minutes to several hours, 0.
Approximately 1 to 2.0 mole peroxide is formed (quantitative by IJ-method). When this peroxide-containing methoxyacetone is heated, acetic acid and methyl formate are produced as by-products, so methoxyacetone peroxidation +! 5! It is presumed that l has a structure in which one hydrogen in the methylene group between the acetyl group and the methoxy group is replaced with a hydroperoxy group KW.

For example, when these solutions are applied in the form of a thin film onto a substrate in an air atmosphere, a cured film can be obtained. We selected linseed oil as the unsaturated compound and applied it in a thin film onto a substrate and compared the curing speed.The results showed that the threads in the methoxyacetone solution cured in a short time to form a film, but the system without methoxyacetone did not cure. No coating was obtained.
