Abstract
PURPOSE: To obtain the titled aqueous dispersion, comprising ethylene, vinyl acetate, and allyl peroxycarbonate, being excellent in film-forming properties, providing insolubilization as well as markedly improved physical properties by heating of the coating film, and being useful as nonwoven fabric binders, paper processing agents, etc.
CONSTITUTION: Aqueous dispersion of copolymers, comprising 4.9W40.0wt% ethylene (A), 95.0W45.0wt% vinyl acetate (B), and 0.1W15.0wt% allyl peroxy carbonate (C) (e.g. t-butylperoxy allyl carbonate, etc.) having the general fomula where R1 is H or 1W4C alkyl; R2 and R3 are 1W4C alkyls; R4 is 1W12C alkyl or 8W12C cycloalkyl, and having the average particle diameter of 0.05W1.0μ. Siad aqueous dispersion is obtained by copolymerization of the dispersion of vinyl acetate and allyl peroxy carbonate in water under the pressure of ethylene in the presence of surfactants or protective colloid, employing a water-soluble radical polymerization initator as catalyst.
