Alpha-Substituted Acyclic Alkanes

8 is the solubility parameter in (cal/mL)1/2, which were calculated by the method ofcomponentcontributions in themanner outlined by Van Krevelen [27]. 

1 is Spol, the solubility parameter of the polymer with respect to I(CH2) H liquids. 

Ph(CH2) Hliquidswithn 3 (Fig. 28). Since methyl bromide is not a liquid at room temperature and atmospheric pressure (the conditions chosen for measuring polymer swelling), C, (empty circle in Fig. 30) was not determined experimentally but rather it was obtained by extrapolation of C for bromoform and methylenebromide and of Log oq, for the Br(CH2) H liquids to methyl bromide as described in Ref. 164. 

The most interesting of the four series is exhibited by the Cl(CH2)nH series [163] the data for the liquids with n 8 of this series (Fig. 31) exhibit a pronounced odd-even alternation above and below a line given by Cn = 1.67 — 0.04n. The Cn data for liquids with n 7 deviate negatively from linearity in the manner exhibited by the other series with phenyl, iodo or bromo in the 1 position (Figs. 29-30).
