Procedure for the preparation of polysulfones and polyethersulfones with reduced Yellowness Index |
| abstract |
Procedure for the preparation of polysulfones with a Yellowness Index according to DIN 6167 less than 19 and polyethersulfones with a Yellowness Index according to DIN 6167 less than 30, characterized in that the polymerization is carried out in basic, aprotic solvents using a stirrer of positive transmission and with very little separation from the wall 5 with d / D> 0.9. |
