| abstract | (57) [Summary] [Structure] For liquid 2-oxetanone, 0.00 1 to 20% by weight of glutaric anhydride, 5- (2,5-dioxotetrahitrofuryl) -3-methyl-3-cyclohexene-1,2-dicarboxylic acid anhydride, or 5-norbornene-2,3-dicarboxylic acid The present invention relates to a composition containing a cyclic carboxylic acid anhydride such as an acid anhydride, which can be stably stored for a long period of time and can be directly used for gas phase polymerization. The composition of 2-oxetanone of the present invention is Suppresses spontaneous polymerization of highly purified 2-oxetanone, Stable storage is possible, high-purity 2-oxetanone can be separated by simple operation such as simple distillation at the time of use without directly reacting with the monomer, and moreover, especially in gas phase polymerization, the composition at the time of polymerization It has a useful property that 2-oxetanone can be directly gasified and subjected to gas phase polymerization. INDUSTRIAL APPLICABILITY According to the present invention, long-term storage stability after purification of 2-oxetanone becomes possible, and poly (2-oxetanone) can be produced at any time. In addition, gas phase polymerization, which is a rational polymerization method that does not use a solvent, has become possible in terms of process. |
