Objectives

1. Prepare solutions to run new PVOH based reactions

General Formula for reactions

Polyvinyl alcohol + [HAc]→Polyvinyl acetate

General Protocol for Polyvinyl acetate synthesis

1. For a 1:1 ratio of polyvinyl alcohol OH groups to polyvinyl acetate dissolve ~1g PVOH inH₂O
2. Add ~1.36g HAc. Add ~2 drops of HCl to reaction mixture to catalyze reaction.
3. Heat the reaction mixture to 40°C.
4. Allow the reaction to stir for 1 hour
5. Add sodium bicarbonate solution to the reaction mixture(titrate the reaction)
6. Rotavap the remaining reaction mixture
