1416574 Polyether sulphonates BAYER AG 12 April 1973 [14 April 1972] 17601/73 Heading C2C [Also in Division C3] Novel compounds of the formula wherein m is an integer of from 1 to 150, M denotes an alkali or alkaline earth metal or an ammonium or alkylammonium radical, R denotes H or methyl, R 1 denotes H, F, Cl, Br, I or C 1-6 alkyl, R 2 denotes H, -NH 2 , -NO 2 , -CN, -CF 3 , Cl or the group with the proviso that where one or both of the radicals R 2 are other than H they must be in the ortho or para position of the benzene ring relative to the ether oxygen group, A denotes one of the radicals R 3 O-, (R 3 ) 2 N-, R 3 N<, R 3 COO-, provided that the R 3 N < definition of A is not applicable when the latter forms part of the group R 2 , R 3 denotes C 1-30 alkyl, aryl, alkylaryl or arylalkyl, R 4 denotes arylene or C 1-30 alkylene and n is 1 or 2, are prepared by converting a compound of the formula in which B denotes HO-, R 3 O-, (R 3 ) 2 N-, R 3 -N<, R 3 COO-, H(-O-CHR.CHR-) m O-R 4 -O-, H(-OCHR.CHR-) m N(R 3 )- or H(-O-CHR.CHR-)O m .CO-R 4 -COO-, into the corresponding alcoholate and reacting the latter at a temperature of 20‹ to 150‹ C. with a compound of the formula wherein " Hal " denotes Cl, Br or F. Compounds having the formulae are disclosed. Uses.-1 to 20% by weight of the above products may be added as antistatic agents to acrylonitrile homopolymers and copolymers with methyl acrylate, sodium methallyl sulphonate and vinyldene chloride, and filaments are spun from dimethyl formamide solution of such polymers.
