发明名称 メタクリル系重合体組成物の製造方法
摘要 A method for producing a methacrylic polymer composition, which comprises a first polymerization step wherein a raw material composition A comprising a raw material monomer A containing no less than 50% by weight of methyl methacrylate, a polymerization initiator A, and a chain transfer agent A is supplied into a first complete mixing type reactor through a supply port of the reactor, and the raw material composition A is subjected to a continuous bulk polymerization in the first complete mixing type reactor, and a resulting intermediate composition is withdrawn through an effluent port of the first complete mixing type reactor; and a second polymerization step wherein a raw material composition B comprising a raw material monomer B containing no less than 50% by weight of methyl methacrylate, a polymerization initiator B, and a chain transfer agent B, and the intermediate composition withdrawn in the first polymerization step are supplied into a second complete mixing type reactor through a supply port of the reactor, and the raw material composition B and the intermediate composition are further subjected to a continuous bulk polymerization in the second complete mixing type reactor, and a resulting methacrylic polymer composition is withdrawn through an effluent port of the second complete mixing type reactor; wherein the formulae (I), (II), (III), (IV) and (V) are satisfied.
