## Abstract To obtain an expression for the entropy __S__ of a polymer network at volume __V__, the assumption is made that a volume __V__~0~ can be defined a which the distribution of endβtoβend distances is the same as in a solution of freely dispersed chains and is Gaussian, and that the distrib
The difference between the vapour pressure of solvent above swollen crosslinked polyurethanes and that above linear polyurethane solutions has been determined experimentally. Comparison of the data over a range of volume fractions of solvent has enabled an estimate to be made of the factor B/A, the
