Continuous production apparatus and continuous production method for polymer
Provided is a continuous production apparatus and a continuous production method capable of preventing the countercurrent of evaporation components generated at the time of polymerization so that continuous solution polymerization reactions can progress reliably. A continuous production apparatus (100) includes a housing chamber (2) configured to house a plurality of reaction vessels (1a to 1d); wherein a reaction mixture is formed by subjecting monomers to a polymerization reaction in a solvent in at least one of the reaction vessels; the reaction vessels communicate with one another via a gas phase part (4); the reaction vessels are sequentially connected; the reaction mixture successively moves to each of the reaction vessels; and the housing chamber includes a baffle (9) configured to narrow the cross-sectional area of the gas phase part at the boundary between at least one pair of adjacent reaction vessels or in the vicinity of the boundary.

METHOD FOR PRODUCING A CROSS-LINKABLE POLYMER WITH THE FORMATION OF OXAZOLIDINONES
The invention relates to a method for producing a polymer comprising the following steps: (A) depositing a radically cross-linkable resin, obtaining a radically cross-linked resin; and (B) treating the radically cross-linked resin under conditions which are sufficient to trigger a chemical reaction that is different from the radical cross-linking in the radically cross-linked resin. The radically cross-linkable resin comprises a curable component, in which there are NCO groups, olefinic CC double bonds and epoxide groups, and the chemical reaction in the radically cross-linked resin that is different from the radical cross-linking is the reaction of NCO groups and epoxide groups to form oxazolidinone groups.
