| titleOfInvention | A kind of method that dimethyl sulfoxide method continuous polymerization prepares polyacrylonitrile solution |
| abstract | This application discloses the polyacrylonitrile solutions that a kind of method of dimethyl sulfoxide method continuous polymerization preparation polyacrylonitrile solution and this method obtain.The method for wherein preparing polyacrylonitrile solution includes the following steps：(1) the first-third comonomer and dimethyl sulfoxide (DMSO) are configured to mixed liquor by a certain percentage；(2) mixed liquor is continuously pumped into polymeric kettle, while the dimethyl sulphoxide solution containing initiator is added drop-wise in polymeric kettle；(3) control temperature of reaction kettle is stepped up to 50~70 DEG C from 25 DEG C, when comonomer conversions are 60~63%, polymer fluid is discharged to terminate reaction；(4) polymer fluid is transferred to de- single device and carries out de- single deaeration processing to get finished product.The application is put forward for the first time synthesizes polyacrylonitrile solution with middle conversion ratio, prevents macromolecule from crosslinking generation gel；The polyacrylonitrile solution molecular weight distributing index D that the application obtains is 1.2~2.0, and isotaxy content is 30~34.5%. |
