Ethylene vinyl alcohol (EVOH) is a formal copolymer of ethylene and vinyl alcohol. Because the latter monomer mainly exists as its tautomer acetaldehyde, the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate (EVA) copolymer followed by hydrolysis.
CH3- is the symbol for methyl group. H3C is also a symbol for the same. It is sometimes written this way to show the direct bonding between the carbon and its neighbouring atom on the right hand. For eg: Methyl alcohol is written as CH3OH (which too is a correct representation of the compound).
