Unlike many vinyl polymers, PVA is not prepared by polymerization of the corresponding monomer. The monomer, vinyl alcohol, almost exclusively exists as the tautomeric form, acetaldehyde. PVA instead is prepared by partial or complete hydrolysis (sometimes referred to in this case as saponification) of polyvinyl acetate to remove acetate groups.

How is polyvinyl acetate made?
Polyvinyl acetate is made by polymerizing vinyl acetate monomers. This is typically done through a free-radical polymerization process in the presence of initiators and stabilizers. The resulting polymer can be further processed to control its properties for various applications such as adhesives, paints, and coatings.
Is slime a natural or synthetic polymer?
it is a synthetic polymer. depends on how you made it
Chemistry of ethylene vinyl acetate?
This is what I've been able to find thus far. Can't find much on ethylene vinyl acetate (EVA), more is available on vinyl acetate (VA). Both are discussed in this study. http://www.chem.tamu.edu/rgroup/goodman/pdf%20files/442_joc-224-04-60.pdf This is the best the EPA has to offer on this. http://www.epa.gov/iris/subst/0512.htm
What compounds are polyvinyl chloride plastic made of?
Polyvinyl chloride (PVC) plastic is made of repeating units of vinyl chloride monomers. These monomers undergo polymerization, where the vinyl chloride molecules link together to form long chains, resulting in the PVC polymer. Additives such as plasticizers, stabilizers, and colorants may also be included to enhance the properties of the PVC plastic.
Does polyvinyl chloride contain any double bonds?
No, polyvinyl chloride (PVC) does not contain any double bonds. PVC is a synthetic polymer made from vinyl chloride monomers through a process called polymerization, which forms long chains of repeating units without any double bonds in its structure.
How is polyvinyl alcohol made and what are the key steps involved in its production process?
Polyvinyl alcohol is made through the hydrolysis of polyvinyl acetate. The key steps in its production process include polymerization of vinyl acetate, hydrolysis of the polymer to form polyvinyl alcohol, purification, and drying.
Polyvinyl acetate made from?
Polyvinyl acetate is made from the polymerization of vinyl acetate monomers. The process involves linking together multiple vinyl acetate molecules to form long chains of polyvinyl acetate, which is a type of synthetic polymer commonly used in adhesives and paints.
How is polyvinyl alcohol made?
Polyvinyl alcohol (PVA) is made by the hydrolysis of polyvinyl acetate, which involves breaking down the acetate groups in polyvinyl acetate to form the alcohol groups in PVA. This process typically involves the use of a catalyst and water to facilitate the reaction. The degree of hydrolysis determines the properties of the resulting PVA polymer.
What is elmer's glue made of?
Elmer's glue is made from polyvinyl acetate and polyvinyl alcohol. Although the exact composition as well as other additives are not exactly known.
How is polyvinyl acetate made?
Polyvinyl acetate is made by polymerizing vinyl acetate monomers. This is typically done through a free-radical polymerization process in the presence of initiators and stabilizers. The resulting polymer can be further processed to control its properties for various applications such as adhesives, paints, and coatings.
What is white glue made of?
White glue is made of polyvinyl acetate
What things are made of polyvinyl?
Polyvinyl materials, such as polyvinyl chloride (PVC), can be used to make a variety of products including pipes, vinyl siding, flooring, and medical devices. Additionally, polyvinyl acetate (PVA) is commonly used in adhesives, paints, and coatings.
Is slime a natural or synthetic polymer?
it is a synthetic polymer. depends on how you made it
Can you use polystyrene with polyvinyl alcohol polyvinyl acetate to make screen photo emulsion?
Polystyrene, polyvinyl alcohol, and polyvinyl acetate are not typically used in screen printing emulsions. Screen emulsions are usually made from light-sensitive compounds like diazo or photopolymer emulsions. These compounds provide the necessary properties for the emulsion to adhere to the screen and create a durable stencil for printing.
What is Elmer's school glue made of?
Polyvinyl acetate.
How to make water proof polyvinyl acetate?
Polyvinyl Acetate (PVAC) IS water proof. Any polyvinyl acetate (PVAC) is made via polymorization of vinyl acetate monomer. The raw material (pvac monomer) liquid is pumped into the reaction tank for polymerization. The reaction is done under normal temperature. Normally it will take hours.
What is pva glue made of?
A chemical called polyvinyl acetate.
