摘要：

The surface tensions of a series of poly(isobutylenes) in the molecular weight range 400-3000 have been determined at 24°C. These results, together with surface tension values from the literature for poly(dimethyl siloxanes) and three series of different pure chain-molecule homologues, are found to exhibit a linear dependence on (molecular weight) -2 2. A simple free-volume argument seems to be consistent with this empirical observation. © 1969.
