Polymer swelling. Part 17: Systematization of steric effects on adsorption parameters as exemplified by swelling of poly(styrene-co-divinylbenzene) to saturation using linear and non-linear acyclic aliphatic ether liquids

The adsorption parameters () for five branched aliphatic ethers were established experimentally in the usual way 17]. It was shown that when this set of -values is combined with the set already established for the unbranched ethers 17], the union set enables one to estimate with reasonable confidence the -values for all the possible structural permutations derivable from the general molecular structure GMS] H(CH₂)_m+1(CH₃)_q′CH_2−q′ OCH_2−q(CH₃)_q](CH₂)_n+1H, and for a portion of those that are derivable from the GMS (CH₃)_q′+1CH_2−q′(CH₂)_mO(CH₂)_n]CH_2−q(CH₃)_q+1, using the corresponding Log vs N linear relationship deduced in these and earlier sorption studies, in which N = m+n+q+q′+4. It was shown that the data for the -values derived thereby comprise a self-consistent rigidly interconnected multidimensional universe of linear Log vs N relationships that represent series of subsets of the above GMSs resulting from varying one integer (m+n+q or ′) while the other three are held constant.
