The adsorption parameters (a) for 10 linear and five branched polyether liquids were established in the usual way.(1-13) These data were then used to deduce the a-values for all the possible structural permutations of the polyethers having general molecular structure (GMS) H(CH2)(m)O(CH2)(c)OCH2-q(CH3)(q)(CH2)(n-1)H (in which m = 1-8, n = m to 8, q = 0-2, and c = 2-12) and those having GMS R’(OCH2CH2)(e)OR (in which e = 1-5 and R’ and R are linear and branched alkyl groups) by systematic incrementation of one of the variables m, n, q, c, or e, the rest being kept constant, as described in the text. The data obtained thereby are consistent with the concept that the diethers are adsorbed asymmetrically to the pendent phenyl groups of poly(styrene-co-divinylbenzene) at liquid-saturation, whereas those having more than two oxygen atoms are adsorbed symmetrically thereto.
