The use of polyvinyl alcohol (PVOH) as a protective colloid in the emulsion polymerisation of vinyl acetate has long been known, as are the advantages conferred on a polyvinyl acetate (PVac) based adhesive by the presence of PVOH, such as suitable rheology, good adhesion to cellulose substrates, setting speed, and high cohesion of the polymer film. However, for some applications the presence of PV...
