Abstract
PURPOSE: To obtain easily a sulfur-containing copolymer which is useful as fiber material etc., by the reaction of a bisacrylamide with a dithiol in the presence of potassium fluoride.
CONSTITUTION: One or two or more (a) of biscrylamides of the formula I (where R1 is H or a monovalent organic group and R2 and R3 are, respectively, a divalent organic group), e.g., N,N'-methylenebisacrylamide, N,N'-isopropylidenebisacryl- amide, etc., are reacted with one or two or more (b) of dithiols of the formula II (where R3 is a divalent organic group), e.g., 1,2-ethanedithiol, 1,4-butanedithiol, etc., in the presence of potassium fluoride at approx. 20W100°C usually. Thus, a sulfur-containing copolymer of a repeating unit of the formula III (where R1, R2, and R3 are the same as in formulas I and II and n is approx. 10W200) can be obtained with economical advantage.
