Polyvinyl acetate is also the raw material to make other polymers like: Polyvinyl alcohol −[HOCHCH 2 ]−: Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. This reversible saponification and esterification reaction was a strong hint for Hermann Staudinger in the formulation of his theory of macromolecules .
Vinyl acetate is an organic compound with the formula CH 3 CO 2 CH=CH 2. This colorless liquid is the precursor to polyvinyl acetate, ethene-vinyl acetate copolymers, polyvinyl alcohol, and other important industrial polymers. [3]
Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH 2 CH(OH)] n . It is used in papermaking , textile warp sizing , as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing .
Polyethylene vinyl acetate has recently become a popular alternative to polyvinyl chloride because it does not contain chlorine. [13] As of 2014, EVA has not been found to be carcinogenic by the NTP , ACGIH , IARC , or OSHA , and has no known adverse effect on human health. [ 14 ]
Polyvinyl esters are a group of thermoplastic vinyl polymers. The most important examples of this group are polyvinyl acetate (PVAC) and polyvinyl propionate . [ 1 ]
Synthetic coagulated or concentrated latices: Polymers such as butadiene-styrene, polyvinyl acetate, polyethylene, paraffin, and petroleum waxes are the most commonly used gum bases on the market today. They are petroleum-derived polymers which are designed to maximize elasticity and incorporate other components of the gum base as well as ...
Because of the instability of vinyl alcohol, the thermoplastic polyvinyl alcohol (PVA or PVOH) is made indirectly by polymerization of vinyl acetate followed by hydrolysis of the ester bonds (Ac = acetyl; HOAc = acetic acid): [8] n CH 2 =CHOAc → (CH 2 −CHOAc) n (CH 2 −CHOAc) n + n H 2 O → (CH 2 −CHOH) n + n HOAc
It is one of the most developed methods in chain-growth polymerization. Currently, most polymers in our daily life are synthesized by free radical polymerization, including polyethylene, polystyrene, polyvinyl chloride, polymethyl methacrylate, polyacrylonitrile, polyvinyl acetate, styrene butadiene rubber, nitrile rubber, neoprene, etc.
