Abstract: Improved compositions for forming pellable films, such as adhesive-release backings, are disclosed which have antistatic characteristics, decreased peeling resistance with respect to adhesives and a more stable peeling efficiency with respect to aging.The improved compositions of this invention comprise a curable mixture of a vinyl-containing organopolysiloxane, an SiH-containing organopolysiloxane and a metal addition-catalyst which has mixed therewith an alcohol- and/or polyether-modified organopolysiloxane.This use of an alcohol- and/or polyether-modified organopolysiloxane provides a decreased static charge, less dust attraction, less blocking and better adhesive coating for the cured pellable film.

Abstract: An improved magnetic recording medium comprising a flexible support consisting of at least about 70 mol % of p-oriented aromatic polycarbonamide units. The polycarbonamide may include substituent groups on the aromatic nuclei. The support has a density of more than about 1.41 g/cm.sup.3 at 25.degree. C and 0% relative humidity, and a tensile modulus higher than about 800 kg/mm.sup.2 in at least one direction, combined with a thin layer of magnetically susceptible material deposited electrically or dispersed in a nonmagnetic binder. The magnetic recording medium in this invention shows excellent running performance and has superior dimensional stability both thermally and hygroscopically.

Abstract: Permselective membranes are prepared by crosslinking synthetic organic polyamides or polyhydrazides having --CO.sub.2 H groups and/or --SO.sub.3 H groups with a salt of metal selected from the class consisting of alkaline earth metals, transition metals, aluminum group metals and lead group metals.The membranes are useful in separating components of fluid mixtures or solutions such as water containing dissolved salts, and are especially useful in producing pure water from saline water.
