Dipolar aprotone dissolvents dimethylsulfoxide

The block-copolymers of polysulfone and polyesters can be also produced [188] by the reaction of aromatic polysulfones in environment of dipolar aprotone dissolvents (dimethylsulfoxide, N-methylpirrolydone, N-methylcaprolactam, N, N -dimethylacetamides or their mixes) with alyphatic polyesters containing not less than two edge OH-groups in the presence of basic catalyst - carbonates of alkali metals Li, Na, K.
