| titleOfInvention | A kind of containing ethylene and the preparation method of vinyl alcohol construction unit copolymer pellet |
| abstract | The present invention is a kind of preparation containing ethylene and the method for vinyl alcohol construction unit copolymer pellet.Described copolymer is ethylene-vinyl alcohol bipolymer or ethylene-vinyl alcohol vinylacetate terpolymer, the step of the method: the preparation of (1) copolymer/alcohol/aqueous solution, (2) preparation of copolymer pellet, the removing of residual catalyst in (3) copolymer pellet.The effect of the present invention is 1) obtain the copolymer solids granule that microchannel is contained in the inside of even particle size, the 0.1 of size adjustable～10mm, micro-pore diameter is 0.005～0.1mm.Filtering and separate simplicity, separation efficiency improves, and dry run is not lumpd, do not produced airborne dust and electrostatic；2) regulation process conditions realize copolymer solids shape, the control of size；3) improve catalyst residual and byproducts removal effect, reduce washing times and water consumption shortens wash time and improves product quality. |
