Abstract

L'invention concerne l'utilisation de dispersions de matière plastique modifiées avec un alcool polyvinylique de viscosité élevée, à base de polymères d'acétate de vinyle, pour coller des panneaux de particules. L'invention est caractérisée en ce que la dispersion aqueuse de matière plastique présente une teneur en matières solides comprise entre 30 et 75 % en poids, par rapport au poids total de la dispersion. Cette proportion de matières solides est constituée de a) 50 à 95 % en poids d'un ou plusieurs polymères d'acétate de vinyle renfermant des groupes carboxyle, b) 4,9 à 49,9 % d'un ou plusieurs alcools polyvinyliques présentant un degré d'hydrolyse compris entre 95 et 100 % en moles et une viscosité Höppler comprise entre 40 et 120 mPas (solution aqueuse à 4 %), et c) 0,1 à 10 % en poids de sels métalliques hydrosolubles d'acides monobasiques présentant une valeur pks < 0, les valeurs indiquées en % en poids étant rapportées respectivement à la teneur totale en matières solides.
