High solids ethylene vinyl acetate emulsions |
摘要 |
<p>In a process for the polymerization of aqueous ethylene vinyl acetate emulsions wherein the polymerization is carried out in the presence of a stabilizing system comprising polyvinyl alcohol and a surfactant, the improvement which comprises using a stabilizing system consisting essentially of 2 to 8% polyvinyl alcohol and 0.25 to 4% of at least one surface-active compound comprising the addition products of 50 to 70 moles of ethylene oxide adducted to straight-chained or branch-chained alkanols or alkylphenols containing 6 to 22 carbon atoms in the alkyl group and having an HLB value equal to or greater than 18.0, the amounts being based on total vinyl acetate.</p> |
