Abstract

1512800 Polyalkylene oxides with terminal urethane groups BAYER AG 30 Oct 1975 [4 Dec 1974] 44917/75 Heading C3R Polyalkylene oxides with terminal urethane groups are obtained by reacting a polyalkylene oxide having at least one hydroxyl group with an N,N-dialkyl or N-alkyl-N-aryl carbamic acid chloride at 100 to 180‹ C. in the absence of a solvent and in the absence of an acid acceptor. In examples ethoxylated stearyl alcohol, an ethoxylated mixture of lauryl, myristic, palmitic and stearyl alcohols and a polyethylene oxide, are reacted with dimethyl carbamic acid chloride.
