摘要
Poly(ether sulfones) (PES) and poly(ether amide sulfones) (PEAS) were prepared from post-consumer polycarbonates and polyesters, respectively, using a single vessel in batch mode (all reactants present when heating was initiated). The depolymerization of the initial polymer occurs concurrently with step growth polymerization to form a product polymer having a number average molecular weight of at least 5000.
