Vinyl acetate (CH3CO2CH=CH2) is a colorless liquid used as the precursor to polyvinyl acetate, an important industrial polymer. It is flammable, mildly toxic and reactive.
Chemicals from Paraffin Hydrocarbons

The main use of acetic acid is to produce vinyl acetate (44%), followed by acetic acid esters (13%) and acetic anhydride (12%). Vinyl acetate is used for the production of adhesives, film, paper, and textiles. Acetic acid is also used to produce pharmaceuticals, dyes, and insecticides. Chloroacetic acid (from acetic acid) is a reactive intermediate used to manufacture many chemicals such as glycine and carboxymethyl cellulose.
Synthesis of Reactants and Intermediates for Polymers

Vinyl acetate was produced by the catalytic acetylation of acetylene, but this monomer is now produced by the catalytic oxidative condensation of acetic acid and ethylene (17.32). Other vinyl esters can be produced by the transesterification of vinyl acetate with higher-boiling carboxylic acids.

Cellulose has attracted increasing attention due to its unique biocompatibility, nontoxic, reinforcement, and environmentally friendly properties.[13–15] As a cellulose derivative, carboxymethyl cellulose (CMC) has good affinity with fibers and can be used to enhance the toughness of paper fibers.[16–19] To make the polymerization proceed smoothly and improve product properties, CMC is modified by acrylic acid (AA) with good chemical stability, heat resistance, and weather resistance.[20–22] Polyacrylate is a functional polymer, and its properties can be adjusted by changing the monomers. As an unsaturated ester, vinyl acetate (VAc) is widely used in the production of thermoplastic polymers, such as protective coatings and adhesive emulsions.[23,24] In the preparation of the acrylate polymer cultural relic protection material, part of acrylate maybe instead by VAc, which has strong adhesion, cheap, and environmental friendliness.[25] However, the water-resistance of vinyl acetate/acrylate copolymer is poor due to the presence of carboxyl and hydroxyl groups in acrylate and VAC. To improve the water-resistance of composite, DFMA containing multiple fluorocarbon chains, strong hydrophobicity and low surface energy, can be introduced to participate in the polymerization.[26–28] Consequently, the synthesis of vinyl acetate/acrylate copolymers modified with carboxymethyl cellulose and fluorine have extensive application prospects for the protection of fragile paper relics.
