What is Polyvinyl acetate?
Polyvinyl acetate (PVAc) is a rubbery synthetic polymer produced by polymerisation of vinyl acetate monomers. It is the primary component of white glue and wood glue (PVA glue). Unlike polyvinyl alcohol (PVOH), PVAc is not hydrolysed and retains its acetate groups. It is an amorphous polymer with a glass transition temperature of about 30 °C, which means it is soft and tacky at room temperature and is used primarily as an adhesive or as a component in paints and coatings.
