PROCESS FOR PREPARING AROMATIC POLYESTERS Russian patent published in 1996 - IPC

Abstract RU 2063404 C1

FIELD: as superconstructional polymeric materials. SUBSTANCE: reaction of nucleophilic substitution of equimolar amounts of polyaromatic nucleophilic reagent with dihalogenaromatic compound is carried out in aprotic solvent while heating in the presence of K₂CO₃ in combination with equimolar mixture of Na₂S•9H₂O and Al₂O₃ or SiO₂ in amount of from 0.5 to 5.0 mole per 1.0 mole of K₂CO₃.. EFFECT: improved properties of the aromatic polyesters.
