Abstract: DONDE: a) UNA MEZCLA DE AGUA, FORMAMIDA, COMPONENTES DE ALTO PUNTO DE EBULLICION Y GASES DISUELTOS SON EXTRAIDOS POR CONDENSACION DEL PRIMER DESTILADO DE LA MEZCLA DE GAS DE PRODUCTO DESPUES DE LA DESHIDRATACION CATALITICA DE FORMAMIDA GASEOSA EN PRESENCIA DE OXIGENO, PARTE DEL AGUA Y LOS GASES DISUELTOS SON SEPARADOS DEL PRIMER DESTILADO PARA DAR UN TERCER DESTILADO QUE COMPRENDE AGUA, FORMAMIDA Y COMPONENTES DE ALTO PUNTO DE EBULLICION, Y UNA CORRIENTE DE RECICLADO CONTENIENDO FORMAMIDA ES SEPARADA DEL TERCER DESTILADO POR DESTILACION SIMPLE; Y, b) HACER RECIRCULAR LA CORRIENDE DE RECICLADO HACIA LA REACCION DE DESHIDRATACION, EN DONDE DICHA CORRIENTE CONTIENE DE 5% HASTA 50% EN PESO DE AGUA. LA DESTILACION SIMPLE SE REALIZA A UNA PRESION DE 0,0204 A 0,153 Kg/cm2 Y A UNA TEMPERATURA DE 110 A 160°C; Y LA DESHIDRATACION CATALITICA A UNA TEMPERATURA DE 400 A 600°C Y A UNA PRESION DE 0,0714 A 0,357 Kg/cm2

Abstract: In a process for preparing ethylene-vinyl acetate copolymers in which a mixture of ethylene and vinyl acetate is polymerized continuously in the presence of free-radical polymerization initiators and, if desired, molecular weight regulators in a cooled tube reactor at a pressure in the range from 1000 to 3500 bar, and the poly-merization initiator is added at the beginning and at two or more points along the tube reactor, and temperature changes in the reaction mixture along the tube reactor, between the first temperature maximum and the last addition of the polymerization initiator, are within a range of not more than 20° C.

Abstract: Temporary protection of surfaces is achieved by application of an aqueous polymer dispersion containing a) at least one C2-C10 olefin, and b) at least one comonomer that may be copolymerized with the olefin under radical conditions. The dispersion layer applied is then dried to give a solid polymer film having a mean thickness exceeding 20 mu m. The invention also refers to coloured polymer dispersions and their use in temporarily protecting or in colouring surfaces.
