Sulfomethylation of high molecular weight polyacrylamide |
| abstract |
Improved methods are provided for the sulfomethylation of high molecular weight polyacrylamide polymers which reduce or minimize cross linking and result in polymers which have a reduced specific viscosity (RSV) greater than the polyacrylamide polymer used as the starting material polymer in the process. |
