## Abstract Thin polymeric films were deposited from siloxane plasma on the surface of polyethylene. The surface composition of the films was measured by X‐ray photoelectron spectroscopy (XPS) and the permeability to O~2~ by an analytic gas permeability fractometer. No significant improvement of ba
Two series of polyurethanes were prepared to investigate the effect of comacrodiol structure on properties and morphology of polyurethanes based on the siloxane macrodiol, ␣,-bis(6-hydroxyethoxypropyl) polydimethylsiloxane (PDMS). All polyurethanes contained a 40 wt % hard segment derived from 4,4Ј-
