| titleOfInvention | Copolymer of diallylamines and sulfur dioxide, and method for producing same |
| abstract | Provided are a copolymer of diallylamines and sulfur dioxide having a high molecular weight and a low content amount of impurities such as halogens, and a production method with which it is possible to produce such a copolymer relatively simply and at low cost. This problem is solved by: a copolymer having a weight-average molecular weight of 150,000 or higher obtained by GPC measurement and a degree of polymerization of 1000 or higher, the copolymer being obtained by copolymerizing sulfur dioxide and a sulfonate or alkyl sulfate salt of diallylamines having a specific structure; and a method for producing a copolymer, the method having a step for copolymerizing sulfur dioxide and a sulfonate or alkyl sulfate salt of diallylamines having a specific structure in ethylene glycol or in propylene glycol monomethyl ether. |
