Abstract

Abstract:

Chloromethylation of phenophthalein polyether sulfone(PES-C) was performed in a homogeneous system using 1,4-bis(chloromethoxyl)butane(BCMB) as the chloromethylation reagent. Chloromethylation of PES-C(CMPES-C) with an appropriate chloromethylation degree and complete linearity was obtained under the optimum reaction conditions. The chemical structures and compositions of the products were characterized by IR and 1H NMR. The chloromethylation degree and properties of CMPES-C, such as solubility in common organic solvents and thermal stability compared with phenophthalein polyether ketone(PEK-C) were also discussed. The chloromethylation degree was determined by 1H NMR integration.

Key words: bis(chloromethoxyl)butane, chloromethylation modification, phenophthalein polyethersulfone
