Abstract
(DE)
Gegenstand der Erfindung ist die Verwendung von Vinylacetat- Isopropenylacetat-Copolymeren als Low-Profile-Additiv (LPA), dadurch gekennzeichnet, dass die Vinylacetat-Isopropenylacetat- Copolymere auf 2 bis 98 Gew.-% Vinylacetat, 2 bis 98 Gew.-% Isopropenylacetat und gegebenenfalls einem oder mehreren weiteren ethylenisch ungesättigten Monomeren basieren, je bezogen auf das Gesamtgewicht der Vinylacetat-Isopropenylacetat-Copolymere.
(EN)
The invention relates to the use of vinyl acetate isopropenyl acetate copolymers as a low-profile additive (LPA), characterized in that the vinyl acetate isopropenyl acetate copolymers are based on 2 to 98% by weight of vinyl acetate, 2 to 98% by weight of isopropenyl acetate and optionally one or more other ethylenically unsaturated monomers, each relative to the total weight of the vinyl acetate isopropenyl acetate copolymers.
(FR)
L'objet de l'invention est l'utilisation de copolymères d'acétate de vinyle - acétate d'isopropényle en tant qu'additif de faible retrait (LPA), caractérisée en ce que les copolymères d'acétate de vinyle - acétate d'isopropényle sont à base de 2 à 98 % en poids d'acétate de vinyle, 2 à 98 % en poids d'acétate d'isopropényle et le cas échéant d'un ou de plusieurs autres monomères insaturés éthyléniquement, à chaque fois par rapport au poids total des copolymères d'acétate de vinyle - acétate d'isopropényle.
