PROCESS FOR PREPARING AROMATIC POLYETHERSULPHONES |
摘要 |
The process for preparing aromatic polyethersulphones by reaction of a dichlorodiphenyl sulphone component with a bisphenol component as monomers, in the presence of alkali metal carbonate, in the melt, in the absence of solvents or diluents, is characterized in that the reaction is carried out in a mixing kneader which is operated with a shear rate in the range from 5 to 500 s-1. |
