Synthesis of PVAc and PVA
2.Objective
PVA(poly vinyl alcohol) is prepared by hydrolysis of PVAc, which is synthesized by emulsion polymerization of vinyl acetate.
3.Theory
◇ Background
-PVA
Polyvinyl alcohol has excellent film forming, emulsifying, and adhesive properties. It is also resistant to oil, grease and solvent. It is odorless and nontoxic. It has high tensile
