SynopsisSpecific volumes at 25' of aqueous solutions of poly (N-methyl acrylamide) and poly-(ethylene oxide) have been measured, and the data obtained is compared with corresponding data on low-molecular-weight compounds. The results support the notion, that the volrrme changes following the interaction between aliphatic groups and water are positive. They are discussed with particular reference to pressure effects on protein conformations.
