Publication number: 20240084059Abstract: Methods for preparing vinyl ester-ethylene copolymers and methods for recovering residual monomers when preparing the same. The method includes performing a stage (a) where radically initiated polymerization of vinyl esters, ethylene and optionally further ethylenically unsaturated monomers in an aqueous medium is performed. In a stage (b) a polymerization mixture from stage (a) is depressurized producing an ethylene-containing gas phase and an aqueous phase containing vinyl esters and vinyl ester-ethylene copolymers. Where the ethylene-containing gas phase separated off, then absorbed into vinyl esters and the mixture thus obtained is used in the radically initiated polymerization of vinyl esters, ethylene and optionally further ethylenically unsaturated monomers.Type: ApplicationFiled: August 27, 2021Publication date: March 14, 2024Applicant: Wacker Chemie AGInventors: Michael ANGERER, Bernhard Eckl

Patent number: 9061922Abstract: A method for processing wastewater and exhaust gas condensates from the polymerization of vinyl acetate and ethylene and optionally other comonomers in an aqueous medium by suspension or emulsion polymerization employs relieving pressure after completion of the polymerization of the polymerization batch and discharging the polymer dispersion. During the relieving, the gaseous phase is removed by means of a compressor. Optionally, the gaseous phase occurring during stripping is removed by the compressor and cooled by one or more heat exchangers before entry into the compressor. The liquid phases occurring in the compressor and optionally in the heat exchanger are separated from the gaseous phase and the liquid phases are given to a rectification column, and separated into a vinyl acetate monomer phase and a wastewater phase, and the vinyl acetate monomer phase is resupplied to polymerization.Type: GrantFiled: May 31, 2012Date of Patent: June 23, 2015Assignee: Wacker Chemie AGInventors: Hans-Peter Weitzel, Bernhard Eckl, Dorothee Guenaltay
