Abstract: A mixing head for multicomponent plastics, especially polyurethane, in whose mixing chamber (2) a hollow piston (7) can be moved to and fro to control the component streams. The hollow piston contains an expulsion piston (8), which is movable independently of the hollow piston, and which can be passed through an outlet tube (3) which adjoins the outlet orifice (4). The end face (12) of the hollow piston forms, together with the mixing chamber wall (11) nearest the sprue, a shearing gap in which the components are mixed. As a result of the design and arrangement of the pistons (7) and (8), good mixing is achievable even under critical conditions, and the mixing chamber is also easily cleaned.

Abstract: Solutions of low viscosity solvents and high viscosity, pasty products, for example water and sodium dithionite formulations, are prepared in a continuous manner in a matter of seconds in static and dynamic mixers connected in series while at the same time the ingress of air is avoided.

Abstract: The invention relates to polyolefin fibrils which have been modified by means of an oxide, hydroxide or silicate of an element from main group II to IV of the periodic table or a sub-group element. They have a high degree of beating and a large specific surface area and are particularly suitable as asbestos substitute. They are prepared from solutions of the polyolefins in an organic solvent which contain the admixed modifier, in a process in which the solutions are either a) heated under pressure and cooled under adiabatic relaxation, during which the fibrils are deposited, or b) introduced into a precipitation bath under the action of shear forces, during which the fibrils precipitate.
