Abstract: A process is described for copolymerizing ethylene with vinyl esters and, if desired, with further vinylic comonomers in a tube reactor at pressures of from 500 to 4000 bar and at not more than 220° C., which comprises initiating the free-radical polymerization at at least two locations of the tube reactor by adding a catalyst/initiator and adjusting the temperature profile within the reactor such that the temperature maxima downstream of the initiation locations are from 150 to 220° C. and differ by less than ±10° C. from one another.

Abstract: A new emulsified wax containing an ethylene/crotonic acid polymerizate forms an excellent component of metallic paints. They are prepared by radical copolymerization of ethylene and crotonic acid in a high pressure autoclave at 160-320 deg C under a pressure of 1000 to 3500 bar in the presence of a regulator such as aliphatic aldehydes or ketones. Independent claims are included for: (1) A process for preparation of aqueous emulsions by emulsification of the wax as above; (2) a floor and carpet cleaning agent containing the aqueous emulsion; (3) a metallic paint containing the wax; (4) a surface coated with the metallic paint; and (5) a process for preparation of metallic paints by mixing of the waxes with hydrocarbons and solvents.

Abstract: Preparation of ethylene polymers (A) by a high pressure process involves dissolving radical initiator(s) in ketone(s) (I); compressing; dosing the mixture to the polymerization reactor in one or more portions; and carrying out polymerization. Preparation of ethylene polymers (A) by a high pressure process involves: (1) dissolving radical initiator(s) in ketone(s) of formula R1-CO-R2 (I); (2) compressing; (3) dosing the mixture to the polymerization reactor in one or more portions; and (4) carrying out polymerization at 140-350 deg C and 400-4500 bars. R1, R2 = 1-6C alkyl or 3-12C cycloalkyl; or are linked to complete a 4-13 membered ring.
