Acrylonitrile copolymer and method for manufacturing it, solution of acrylonitrile copolymer and polyacrylonitrile fiber precursor for carbon fiber and method for manufacturing the same |
| abstract |
An acrylonitrile copolymer comprising a sulfonate group derived from a polymerization initiator, in an amount of 1.0 x 10-5 eq / g or more, wherein the value (equivalent ratio) of the sulfate group content derived from the initiator of the polymerization / total content of sulfonate group and sulfate group is 0.4 or less, and wherein the content of sulfonate group is an amount such that the total content of sulfonate group and sulfate groups in the acrylonitrile copolymer is less than 4.0 x 10-5 eq / g. |
