Vinyl alcohol is unstable and readily tautomerizes to acetaldehyde, making it difficult to isolate and utilize for polymerization. As a result, vinyl acetate is typically used as the monomer for the synthesis of polyvinyl alcohol (PVA) through hydrolysis.
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.
The chemical formula of polyvinyl alcohol (PVA) is (C2H4O)n, where n represents the number of repeating ethylene (C2H4O) units in the polymer chain.
0.5 g of Polyvinyl Alcohol in 10 mL of water, heating in water (80 degree C, low solubility below 60 degrre C) with stirring for 15min, then cool it to room temperature and another 4-5 hours of stirring at ambient temperature should give you a homogenous solution.
I am just trying to find out the same thing. I know it's produced by reacting the monomer vinyl alcohol (CH2-CHOH) with acetic acid.You can make PVA gl ue by adding flour water and mix it together and and put it in the fridge when you need it take it out of the fridge and add little water to it so it looks like it's running.Yoo can also make pva glue by mixing flour and milk to make a thicker paste :D
When PVA (polyvinyl alcohol) and borax are mixed together in water, a cross-linking reaction occurs between the PVA polymer chains and the borate ions. This cross-linking reaction forms a gel-like substance, commonly known as slime, due to the formation of borate ester bonds. The process is often used in making homemade slime as a fun and educational experiment.
