ABSTRACT:
A process for producing an inorganic-organic composition material based on gypsum and polyurethane comprising exposing calcined gypsum or anhydrite to the action of water in the presence of a polyurethane or polyurethane-urea which is dispersible in water and in the presence of up to about 20% by weight (relative to the total mixture) of an alcohol and up to about 20% by weight (relative to the total mixture) of another organic solvent, and allowing the composition to set while permitting any solvents which may be present to evaporate. The calcium sulphate may be on a textile support or the composition may be molded into flexible shaped articles of good mechanical properties.
