Vinylpyrrolidone-based polymer composition |
| abstract |
Disclosed is a vinylpyrrolidone-based polymer composition which has improved storage stability and of which the reduction in the molecular weight (K value) under shear stress is small. The composition comprises a vinylpyrrolidone-based polymer and contains from 1 to 10000 ppm of at least one compound selected from a group consisting of biguanides and further contains from 1000 to 30000 ppm of 2-pyrrolidone and from 1 to 5000 ppm of ammonia. |
