1,203,869. Antistatic polymer compositions; silicon modified polyoxyalkylenes. FARBENFABRIKEN BAYER A.G. 4 Dec., 1968 [28 Dec., 1967], No. 57548/68. Headings C3R and C3S. Antistatic articles are formed from a synthetic polymers, e.g. polycaprolactam, containing 0.2 to 30% by weight of a silicon compound. in which R 1 is a C 6-26 alkyl radical, R 2 and R 3 are C 1-4 alkyl radicals, OR 1 or Y; Y represents the radical in which R 4 is H or methyl and n is 5-250. In preferred Si compounds R<SP>1</SP> is stearyl. The compounds may be prepared by reacting stearyl alcohol with trichloromethyl silane followed by reaction with polyethylene glycol.
