Preparation and characterization of poly[oxy(2,6‐dimethyl‐1,4‐phenylene)] with functional end groups

Abstract

Abstract The oxidative polymerization of 2,6‐dimethylphenol ( 1 ) and the halogen displacement polymerization of 4‐halo‐2,6‐dimethylphenols ( 4 ) yielded poly[oxy(2,6‐dimethyl‐1,4‐phenylene)] ( 2 ) with one phenolic end group. 2,2′,6,6′‐Tetramethyl‐4,4′‐isopropylidenediphenol ( 9a ) was used as comonomer in both polymerization reactions to obtain polymer 10a , containing two phenolic end groups. Polymers of different molecular weight were synthesized by variation of the mole ratio of the comonomers. The polymers were characterized by GPC, NMR spectroscopy and end group analysis.
