摘要：

The composition of Coe-Soft, a soft liner, has been determined. The polymer powder is essentially polyethyl methacrylate and the liquid is a mixture of dibutyl phthalate, benzyl salicylate and ethanol. The diffusion of ethanol out of Coe-Soft into air proceeds by two processes and their rates have been measured. On immersion in water the ethanol diffuses out by the faster process at the same rate as into air. Subsequently water is absorbed without limit and equilibrium is not attained even after 131 days (4·68 months). © 1979.
