Abstract
The process consists of (a) preparing an anisotropic soln. capable of forming fibres and films of at least one cellulose deriv. which includes cellulose ester gps. at least part of which are formate gps.; and (b) regenerating at least part of the cellulose in the article obtained. The solution is made by mixing a cellulosic material, at least one cpd. selected from mono-carboxylic organic acids, anhydrides or acid chlorides, and phosphoric anhydride
