Abstract
Phenol polyether alcohols of the formula HOR(OCH2CHOHCH2OR)zOCH2CHOH CH2OROH wherein R is the divalent radical of a dihydric phenol R(OH)2 and z is 0 or an integer are prepared by reacting z+2 mols. of the dihydric phenol with z+1 mols. of epichlorohydrin in the presence of caustic soda. In examples phenol polyether alcohols in which z=0, 1, 2 and 3 are prepared from bisphenol A and a phenol polyether alcohol in which z=2 is prepared from resorcinol.ALSO:Polymeric glycidyl polyethers are prepared by reacting (1) a complex phenol polyether alcohol of formula HOR(OCH2CHOHCH2OR)zOCH2CHOHCH2OROH wherein R represents the divalent radical from a dihydric phenol R(OH)2 and z is O or an integer up to 10, with (2) a molar excess of an epihalohydrin in the presence of a caustic alkali as a dehydrohalogenating agent, the number of mols. of epihalohydrin being x(z+2), wherein x is a number from 1.5 to 10. The complex phenols used are the reaction products of a dihydric phenol (in excess) and either an epihalohydrin or a diglycidyl ether of a dihydric phenol. The complex phenol and epihalohydrin may be condensed in the presence of an alkaline material before dehydrohalogenation with an alkali metal hydroxide or both reactions may be performed in one step in the presence of an alkali metal hydroxide.
