In this contribution we analyze sorption and transport of several gases in semicryst. syndiotactic polystyrene with nanoporous cryst. d form.

Abstract

In this contribution we analyze sorption and transport of several gases in semicryst. syndiotactic polystyrene with nanoporous cryst. d form. Investigation was performed on amorphous samples and on samples characterized by different degrees of crystallinity. Sorption isotherms of carbon dioxide, nitrogen and oxygen in the cryst. phase have been detd. starting from exptl. results obtained for semicryst. and amorphous samples. Corresponding isosteric heats of sorption were evaluated for the cryst. and amorphous phase. Permeation tests were also performed to gather information on mass transport properties of semicryst. samples, evaluating av. diffusivities of carbon dioxide and oxygen, in the limit of small concns. as function of degree of crystallinity.
