Abstract: Process for producing fibrils (short fibres) by introducing solutions of vinyl chloride, vinylidene chloride or styrene polymers into tetrahydrofuran, 1,4-dioxane or methyl ethyl ketone in, for example, water under the action of shearing forces, the polymer solutions used being such additionally containing oxides, silicates, carbonates or sulphates of di- to tetravalent metals, preferably calcium oxide, calcium hydroxide, alumina, calcium silicate, silica, cement produced therefrom, silicon tetrachloride and/or the reaction product of cement or calcium oxide with silicon tetrachloride in an amount of 1 to 900% by weight, relative to the solid polymer, and fibrils obtained by this process.
