发明名称 Branched aromatic sulfide/sulfone polymer production
摘要 A first reaction mixture of at least one dihalo aromatic sulfone, at least one polyhydroxy aromatic compound, at least one organic amide and at least one alkali metal carbonate is contacted under polymerization conditions including a period of time at a temperature sufficient to form a reaction product, with the resulting product mixture being contacted with at least one polymerizable sulfur source, at least one organic amide, at least one alkali metal carboxylate, and water under polymerization conditions including a period of time at a temperature sufficient to form a branched aromatic sulfide sulfone polymer. The resulting polymers are useful in the production of coatings, films, molded objects, and fibers.
