[2] Preliminary. Source: Foreign Commerce and Navigation of the United States. Competitive conditions. Domestic consumption of vinyl acetate and vinyl chloride has increased in recent years from experimental to commercial quantities. Many years of intensive research looking toward large outlets for the resins made from these compounds has apparently been successful. The largest single application indicated at this time is for safety glass sheets. The large increase in domestic consumption expected in the immediate future will probably be supplied chiefly from expanding domestic production and imports from Canada will probably decline even under the reduced trade-agreement duty except to fill possible temporary shortages.
