Title:
高沸点ビニルエステルのわずかな含分を有するビニルアセテート-ビニルエステル-混合ポリマーの製造
Document Type and Number:
Japanese Patent JP2011510099
Kind Code:
A
Abstract:
The invention relates to a method for the production of vinyl acetate-vinyl ester copolymers having a low content of high-boiling vinyl esters by the radically initiated polymerization of 4.9 to 95 wt.-% vinyl acetate, 4.9 to 95 wt.-% of one or more high-boiling vinyl esters, and optionally 0.1 to 40 wt.-% of one or more ethylenically unsaturated auxiliary monomers, characterized in that additionally 0.1 to 40 wt.-% of vinyl acetate is added at a conversion rate of the polymerization of 65 to 99.9%, wherein the amounts given in wt.-% each refer to the total weight of the monomers, and add up to 100 wt.-%.
