NOVELTY - Copolymer of ethylene and at least one carboxylic acid vinyl ester in which ethylene is at least partly obtained from renewable raw materials, is claimed.    USE - The copolymer is useful: as an adhesive or adhesive composition, preferably in coextrusion, extrusion coating or extrusion lamination, where the adhesive composition is useful in a multilayer structure or as a sealing layer; as a compatibilizing compounds or impact modifier in polymers; to form films, preferably encapsulating films for solar panels and resilient flooring; as an additive in oil or fuel; for the manufacture of soundproofing mass of flexible parts such as tubes or bottles, electric cable sheath and ink; for manufacturing woven or non-woven textiles; and for modification of bitumen or thermofusible adhesive (all claimed). The composition is useful for making medium or high voltage cables and for producing masterbatches.    ADVANTAGE - The process avoids using ethylene, which is highly reactive and causes oligomerization side reactions. The process can be implemented in production units located on the place of production of raw materials. The size of production units of the process is much smaller than the size of a refinery, which are indeed large facilities usually located far from centers of production and raw materials supplied by pipelines. The process is economical.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) preparing copolymer of ethylene and at least one carboxylic acid vinyl ester comprising: fermentation of renewable raw materials and optionally purification to produce at least one alcohol or its mixture comprising ethanol; dehydration of the resulting alcohol to produce at least one alkene or its mixture comprising ethylene and, optionally purification of alkene to obtain ethylene; copolymerization of ethylene with at least one comonomer comprising carboxylic acid vinyl ester; and isolation of the obtained copolymer;    (2) preparing a terpolymer of polyethylene, at least one vinyl ester and unsaturated carboxylic acid anhydride comprising: fermentation of renewable raw materials and optionally purification to produce at least one alcohol comprising ethanol and mixtures of alcohols including ethanol; dehydration of the resulting alcohol to produce at least one olefin comprising ethylene and mixtures of alkenes consisting of ethylene and, optionally purifying the alkene to obtain ethylene; copolymerization of ethylene with at least one vinyl ester and at least one unsaturated carboxylic acid anhydride; and isolation of the obtained copolymer; and    (3) a composition comprising the copolymer or obtained by the process, where the composition further comprises at least one additive comprising antioxidants, UV protection agents, implementation agent, anti-fog agent, anti-blocking agents, filler, coupling agents, crosslinking agents, antistatic agents, nucleating agents, pigments, colorants, plasticizers, thinner or flame retardant additives.
