ABSTRACT:
The invention relates to a coagulable composition, to a process for the preparation of a coagulated material by impregnating a textile cloth in an impregnating bath containing the coagulable composition followed by coagulation in a coagulating bath and to the resulting coagulated material.
The process of the invention is characterized in that the coagulation is carried out from the water phase, and the impregnating bath contains a chemical or physical foaming agent, wherein foaming occurs simultaneously with the coagulation or immediately thereafter.
It is surprisingly found that according to the present invention a high quality coagulated material is obtained, having properties comparable with the coagulated material obtained according to conventional solvent based processes.
