Vinyl ester resin, or often just vinyl ester, is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. [1] The "vinyl" groups refer to these ester substituents, which are prone to polymerize and thus an inhibitor is usually added.
Vinyl neodecanoate (trade name VeoVa 10) is a vinylic monomer that is virtually always used in combination with other monomers to create latices or emulsion polymers. [3] The trade name is an acronym of Vinyl ester of Versatic Acid with the number 10 meaning 10 carbons in the molecule. It has a medium to low glass transition temperature of -3 °C.
Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde.
Vinyl ester resins made by addition reactions between an epoxy resin with acrylic acid derivatives, when diluted/dissolved in a vinyl functional monomer such as styrene, polymerise. The resulting thermosets are notable for their high adhesion, heat resistance and corrosion resistance.
Vinyl acetate is the acetate ester of vinyl alcohol. Since vinyl alcohol is highly unstable (with respect to acetaldehyde), the preparation of vinyl acetate is more complex than the synthesis of other acetate esters. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. [6]
EVA is made by mixing ethylene and vinyl acetate in a processor, which creates an unrefined mass of EVA. It is fed through rollers that flatten it into sheets, which are then put into a pressure oven. [2] Ethylene-vinyl acetate is based on products from the production of petroleum and natural gas.
DMA serves as a promoter in the curing of polyester and vinyl ester resins. [10] DMA is also used as a precursor to other organic compounds. A study of the in vitro metabolism of N,N -dimethylaniline using guinea pig and rabbit preparations and GLC techniques has confirmed N -demethylation and N -oxidation as metabolic pathways, and has also ...
[9] [10] The manufacturing of epoxy resins and vinyl ester resins account for 25–30% of BPA use. [9] [10] The remaining 5% is used as a major component of several high-performance plastics, and as a minor additive in PVC, polyurethane, thermal paper, and several other materials. It is not a plasticizer, [11] although it is often wrongly ...
