An aqueous latex of a poly ([beta]-hydroxyalkanoate) (PHA) coated on paper imparted water imperviousness without changing mechanical properties. Hot-pressed films biodegraded faster than solvent cast films. The PHA coating on paper degraded totally in activated sludge within 12 days, leaving the cellulose matrix relatively untouched. Blends of PHA latexes with sodium carboxymethl cellulose, polystyrene latex, carboxylated styrenel butadiene latex, natural rubber latex, carboxylated styrenel butadiene latex; natural rubber latex, and starch powders form satisfactory films at room temperature.
