Method of producing dry polyvinyl acetate particles that are readily dispersible in water, are vinyl acetate substantially monomer-free and are useful for making polyvinyl ace tate dispersion compositions that are low in odor, form clear dried films and may be used in adh esives, sealants, caulks and coatings. The method includes manufacturing an aqueous, e.g. water, dispersion of polyvinyl acetate containing polyvinyl alcohol; drying to remove volatiles by co nverting the dispersion to dry form under controlled temperature conditions and redispersing the dried polyvinyl acetate particles in an aqueous medium to form a polyvinyl acetate dispersion th at is substantially free of vinyl acetate monomer.
