Abstract

279,047. I. G. Farbenindnstrie Akt.- Ges. Oct. 16, 1926, [Convention date]. Apparatus for making films.-The surface of the support consisting of a cellulose derivative, used as a base for the manufacture of films, is subjected to a treatment such as saponification, denitration &c., so that the support neither swells nor dissolves in the solvent which is used for making the film-dope. In the case of a nitrocellulose support treatment with a solution of sodium hydrosulphide or ammonium sulphide may be employed. The treatment is such that the cellulose ester or ether is converted superficially into regenerated cellulose.
