| abstract | (57) [Summary] (Modified) [Constitution] The inner surfaces of the polymerization equipment such as the surface of the polymerization vessel and the surface of the agitator are tetrafluoroethylene resin, tetrafluoroethylene-ethylene copolymer resin, heptadecafluorodecyltriene. Coated with a compound having a non-polar group such as methoxysilane, and the whole or part of the device with tetrafluoroethylene resin, Made from a resin with a non-polar group such as tetrafluoroethylene-hexafluoropropylene resin or polyethylene, or a compound or resin with a non-polar group such as tetrafluoroethylene resin, polypropylene or heptadecafluorodecyltrimethoxysilane The 2-oxetanone is polymerized using a polymerization initiator in a depolarized polymerization apparatus by, for example, installing an inner container having a surface defined in 1. in the polymerization apparatus. [Effect] By making the inner surface of the polymerization device non-polar, it is possible to prevent the monomer and polymer from adhering to the inner surface of the polymerization container, the stirring device, and the gas phase portion, suppress abnormal polymerization, and perform more uniform polymerization . |
