Quick Details
Specifications
the Polyvinyl acetate, PVAC, is a rubbery
Synthetic polymer with the formula(C4H6O2)n.
It belongs to the polyvinyl esters family with the general formula -[RCOOCHCH2]-. It is a type of
Thermoplastic.
1.2 Chemical Properties
the degree of polymerization of polyvinyl Acetate typically is 100 to 5000. the ester groups of the polyvinyl acetate are Sensitive for alkali and will slowly convert PVAC into polyvinyl alcohol and Acetic acid.
under alkaline conditions, boron compounds, Such as boric acid or borax causes the polymer to cross-link forming tackified Precipitates or slime
