摘要

integrated process for the production of ethylene and butylene copolymers, ethylene and butylene copolymer, and, use of ethylene and 1-butylene the present invention relates to integrated processes for the production of ethylene and butylene copolymers from at least one material renewable natural raw material. more specifically, the present invention deals with processes where the ethylene monomer, used in the polymerization to produce a copolymer of ethylene and 1-butylene, such as the comonomer, is obtained through the dehydration reaction of ethanol produced from the fermentation of sugars , and 1-butylene is obtained through at least one of the following reactions: (i) dehydration reaction of 1-butanol produced directly by fermentation of sugars; (ii) dehydration reaction of 1-butanol produced by chemical route from ethanol obtained by fermentation of sugars; and / or (iii) ethylene dimerization reaction from the. dehydration of ethanol obtained from the fermentation of sugars, and subsequent isomerization reaction of the formed 2-butylene isomers. the ethylene-butylene copolymer thus produced is completely based on carbon atoms originating from renewable natural raw materials and, during incineration, co2 from a non-fossil origin is produced.
