| titleOfInvention | Composite polymerization method |
| abstract | An object of the present invention is to efficiently obtain a target polymer in each of a plurality of polymerization reaction steps while effectively using the monomer without imposing a burden on purification of the monomer recovered from one polymerization reaction step. Provided is a composite polymerization method capable of A first polymerization reaction step in which a first raw material monomer containing a polymerization inhibitory compound is polymerized until a polymerization conversion rate α is reached, from a polymerization reaction product obtained in the first polymerization reaction step Separation step for separating the polymer and recovering the unreacted first raw material monomer and the polymerization inhibitory compound, the unreacted first raw material containing the polymerization inhibitory compound obtained in the separation step Second polymerization reaction step in which the polymer is used as a part of the second raw material monomer and polymerized until the polymerization conversion rate of the second raw material monomer is β (where β> α) A composite polymerization method comprising: [Selection] Figure 1 |
