ABSTRACT:
The present invention is a composition comprising either: a) a high internal phase ratio emulsion having water as a continuous phase and a thermoplastic hydroxy-functional polyether as a disperse phase; or b) a stable aqueous dispersion of the thermoplastic hydroxy-functional polyether. The composition of the present invention addresses a need in the art by providing a thermoplastic coating that exhibits an excellent barrier to oxygen and carbon dioxide, but which barrier properties are not adversely affected by contact with water. The composition is particularly useful in the paper packaging industry where biodegradability and resistance to spoilage of food is desirable.
