United States production.

Until 1938 the one domestic maker of vinyl acetate produced only experimental lots, the bulk of our requirements being imported from Canada. In that year large units to manufacture vinyl acetate were built at Niagara Falls, N. Y., and at Belle, W. Va. The remarkable properties of safety glass made from vinyl resin sheets, together with several other new and important applications of these resins, indicate a demand for vinyl acetate sufficient to warrant these large manufacturing units. The United States patents covering the processes of manufacture of vinyl acetate are owned by the Canadian producer, who has licensed the domestic makers.

Domestic production of vinyl chloride has increased from experimental quantities in 1927 to large-scale commercial output, increasing substantially each year since 1933.

United States imports.

There has been no import of vinyl chloride. Imports of vinyl acetate (unpolymerized), entirely from Canada, are shown in table [91].
