    Abstract: A method for producing a breathable film based on polyvinyl chloride (PVC), including the following steps. Preparing a paste-like compound including a first fraction composed of PVC, a second fraction composed of a foreign material, and a third fraction composed of adjuvants and/or additives that that are mixed together to form the paste-like compound, applying the paste-like compound to a base, and drying and gelling the paste-like compound, which has been applied to the base, through the addition of heat, thus forming the film in which pores extending from the one surface of the film to the other are formed, which give the film breathability.

    Abstract: A method of manufacturing porous core-shell polymer particles having a nonporous shell including: providing a first organic solvent containing a dissolved polymer; dispersing the organic solvent in an aqueous phase containing a stabilizer to form an emulsion; adding the emulsion to a second organic solvent wherein the second organic solvent is miscible with water and the first organic solvent, and a non-solvent for the polymer; and evaporating the first and second organic solvents from the emulsion to form core-shell polymer particles. The method results in core-shell polymer particles comprising a common binder polymer for the core and the shell wherein the core has a porosity and the shell is non-porous. The particles have a porosity from 10 to 70 percent.
