Abstract: Organosilicon binders are prepared by mixing organosilanols or condensation products or reaction products thereof containing either hydroxyl or alkoxy groups with either an organometallic silanolate or organometallic siloxanate containing Ca, Al, Fe or Mg; the examples relate to organometallic compounds of Ca. The binder may also contain a filler. This may react with the system, e.g. cement or may be a passive filler. The latter may, e.g. be metal oxides, glass, asbestos, ceramic materials, cellulosic materials. Other polymers, e.g. condensation polymers: polyesters, polyamides, polycarbonates, phenoplasts or aminoplasts or addition polymers of: olefins, styrene, vinyl chloride, acrylic acids and esters may be used.

Abstract: A METHOD OF AFTER-TREATING HIGH-PRESSURE POLYETHYLENE IN SHEARING UNIT, WHEREIN THE HIGH-PRESSURE POLYETHYLENE IS INTRODUCED INTO THE SHEARING UNIT AT 200* TO 300*C. AND A VISCOSITY OF 5X10**3 TO 1X10**5 POISES AND SUBJECTED TO A SHEARING GRADIENT, THE SHEARING SURFACES CONTACTING THE POLYETHYLENE MELT BEING HEATED A TEMPERATURE WHICH IS AT LEAST AS HIGH AS THAT OF THE POLYETHYLENE MELT AND THE POLYETHYLENE MELT BEING SHEARED AT SUCH A SHEARING SPEED THAT THE PRODUCT OF SHEARING SPEED AND RESIDENCE TIME IN THE SHEARING ZONE IS EQUAL TO 5X10**2 TO 5X10**4.
