METHOD OF MAKING THE ACRYLOUS POLYMERES WITH HIGH SWELLING CAPACITY |
| 摘要 |
This invention relates to a process for the preparation of acrylic polymers which are at least for the most part insoluble in water and have a high swellability in water, by reacting polyacrylonitrile or copolymers based on acrylonitrile at a temperature exceeding 100 DEG C. with aqueous-alkaline solutions which may contain an organic solvent which is miscible with water. |
