| Firstly, each polyvinyl acetate is made by solution polymerisation, and then the resulting polyvinyl acetate is hydrolysed rapidly in methanol, ethanol or a mixture of ethanol and methyl acetate using alkali metal or acid-free as a catalyst. Alcoholysis is carried out to obtain polyvinyl alcohol | |||
