    Abstract: PROCESS FOR THE MANUFACTURE OF ETHYLENE COPOLYMER DISPERSIONS BY COPOLYMERIZING ETHYLENE WITH ALKALI METAL SALTS OF ONE OR MORE MONO-UNSATURATED ACYLASMIDE-N-SULFONIC ACIDS OF THE FORMULA R1CH=C(R2)CONH-SO3H, WHEREIN R1 AND R2 EACH REPRESENTS A HYDROGEN ATOM OR AN ORGANIC RADICAL CONTAINING 1 TO 10 CARBON ATOMS. IF NECESSARY, FURTHER COPOLYMERIZABLE COMPOUNDS MAY BE USED ADDITIONALLY. THE COPOLYMER DISPERSIONS OF THE INVENTION MAY BE USED FOR COATING PLASTICS MATERIALS, WOOD, PAPER AND THE LIKE AS WELL AS FOR IMPREGNATING OR FINISHING PAPER, FELT OR FIBROUS MATERIALS.

    Abstract: A PROCESS FOR THE PREPARATION OF PULVERULENT COPOLYMERS PREPARED BY SAPONIFYINGB ACRYLAMIDE-N-SULFONIC ACIDS CONSISTING OF ETHYLENE STRUCTURAL UNITS AND VINYL-AMIDE STRUCTURAL UNITS, AND POSSIBLY FURTHER STRUCTURAL UNITS OF ETHYLENICALLY MONO-UNSATURATED COPOLYMERIZABLE MONOMERS. THE MODIFIED POLYETHYLENE POWDERS OBTAINED IN ACCORDANCE WITH THE INVENTION ARE EXTREMELY SUITABLE FOR THE POWDERING OF RUBBER SHEETS AND/OR RUBBER GRANULES, FOR WHIRL-SINTERING COATIG, AS TEXTILE REINFORCEMENT TO BE IRONED INTO THE MATERIAL, AS A SUPPORTING BASE FOR PIGMENT PREPARATIONS, AS POWDER BASE FOR PHARMACEUTICAL OR COSMETIC PREPARATIONS, AS A LUBRICANT FOR THE TABLET MANUFACTURE, AS WELL AS ADDITIVES TO POLYESTER AND POLYVINYL CHLORIDE EXTRUSION MATERIAL IN ORDER TO INCREASE THE FLOW PROPERTY IN THE EXTRUSION PROCESS AND TO IMPROVE THE IMPACT STRENGTH OF SUCH POLYMERS.

    Abstract: HOE 86/F 223 The invention relates to a process for the preparation of vinylphosphonic dichloride through elimination of hydrogen chloride from 2-chloroethanephosphonic dichloride in the presence of catalysts. The catalysts used are tertiary phosphines, quaternary ammonium or phosphonium salts or alkali metal or alkaline-earth metal halides. When triphenyl phosphine is used as the catalyst, the reaction is carried out under reduced pressure at a temperature of 130 to 166.degree.C and the vinylphosphonic dichloride produced is simultaneously removed by distillation under reduced pressure. When the other catalysts are used, the process can be carried out at atmospheric pressure or reduced pressure and at temperatures of about 130 to 220.degree.C and the vinylphosphonic dichloride produced can be removed by distillation simultaneously with or subsequent to the reaction.

    Abstract: HOE 86/F 224 The invention relates to a process for the preparation of vinylphosphonic dichloride, in which a 2-chloroethane-phosphonate of the formula or or a mixture of the two esters, is reacted with thionyl chloride at a temperature of 60 to 160.degree.C in the presence of a catalyst which contains tertiary phosphines, quaternary ammonium or phosphonium salts or alkali metal or alkalineearth metal halides. During this reaction, any thionyl chloride which may be present is removed by distillation subsequent to this reaction, the mixture remaining is heated to 140 to 200.degree.C, and the vinylphosphonic dichloride produced during this is removed by distillation.
