摘要： A vinyl acetate-ethylene (VAE) copolymer and uses of the same are provided. The vinyl acetate-ethylene (VAE) copolymer includes a structural unit derived from ethylene and a structural unit derived from vinyl acetate. The 1H-NMR spectrum of the vinyl acetate-ethylene (VAE) copolymer has an integral value B of signals from 0.5 ppm to 1.0 ppm and an integral value A of signals from 4.6 ppm to 5.0 ppm, and the value of B/3A ranges from 0.070 to 0.120. The 1H-NMR spectrum is measured by using dimethyl sulfoxide as a solvent.

摘要： Controlling the shutdown of a polyethylene reactor system that includes a secondary compressor, a reactor, a high pressure let down valve (HPLDV), a high-pressure separator, and a high-pressure recycle gas system is provided. After a partial or complete shutdown of secondary compressor, HPLDV opens to a pre-set open position until the reactor pressure reduces to either a pre-set reduced pressure limit or a until the slope of the reactor gas density to reactor pressure exceeds 0.15. The HPLDV controls the pressure to a pressure set point.

摘要： A polymerization reactor for producing aqueous polymer dispersions by radically initiated emulsion polymerization of one or more ethylenically unsaturated monomers in the presence of one or more protective colloids and/or emulsifiers, is cleaned by initially charging an aqueous mixture comprising one or more ethylenically unsaturated monomers, one or more protective colloids and/or emulsifiers, but no oxidation initiator, the proportion of ethylenically unsaturated monomers being 20 to 70% by weight of the aqueous mixture, heating the aqueous mixture to a temperature of 50° C. to 100° C. for 5 minutes to 3 hours, adding one or more initiators and optionally further starting materials, initiating polymerization, removing the aqueous polymer dispersion thus obtained from the polymerization reactor and post-treating the dispersion to remove wall deposits detached during the process.
