    摘要: High solids content aqueous vinyl acetate emulsions having long term stability are provided by polymerizing vinyl acetate in the presence of a surfactant of the formula
    wherein:

    R, is an alkyl group having from 6 to 18 carbons;
    R 2 is H or an alkyl group having from 6 to 12 carbons;
    n is greater than 9; and

    Me is a monovalent cation selected from the group consisting of NH., Na, Li and K, and water. The quantity of water is predetermined so as to produce a latex having at least 40% solids.
    Also the production of these emulsions and the stated surfactants are object of the invention.
