Segmented polyurethane-ureas were prepared from low-molecular weight homopolymers or triblock (PEP ) copolymers of ethylene and propylene oxides and 4,4'-diphenylmethane diisocyanate with hydrazine as chain extender. Equilibrium sorption of water vapor at 23ยฐC was measured at eight to nine values of

## Abstract Heats of water vapor sorption by three biopolymers, polygalacturonic acid, sodium hyaluronate, and calcium salt of bovine submaxillary mucin, were determined calorimetrically. These calorimetric heats of sorption were compared with the isosteric heats of sorption as a function of water
The sorption of nitrogen, water vapor, and benzene on a phenyl-Preliminary nitrogen sorption studies (1) suggested that the modified MCM-41 type sorbent has been studied. Nitrogen sorpmaterial prepared using 20 mol% PTES in the initial synthetion is characterized by a Type I isotherm indicating micr
Abstrac~ Sorption isotherms of water vapour were determined for crosslinked poly-2-hydroxyethyl methacrylate (PHEMA), poly-2-(2'-hydroxyethoxy)ethyl methacrylate (PHEOEMA) and statistical copolymers at 35'. In the case of PHEMA the amount sorbed does not depend on the porosity of structure: sorption
