Beschreibung
Zusammenfassung:	The present invention provides the use of hydrophobized polyethyleneimine for improving the adhesion of a fibre material to rubber in a rubber composite, wherein the hydrophobized polyethyleneimine has been hydrophobized to provide substituents which carry one or more pendant reactive groups. Included in this invention are a method for improving the adhesion of the fibre material to rubber in a rubber composite; a coated fibre material comprising a coated hydrophobized polyethyleneimine; a rubber composite comprising rubber and a fibre material, in which the fibre material has a coating of hydrophobized polyethyleneimine; methods for producing the coated fibre material and for producing the rubber composite; and aqueous formulation, suitable as a dipping solution, used for improving the adhesion of the fibre material to a rubber in a rubber composite. La présente invention concerne l'utilisation de polyéthylèneimine rendue hydrophobe pour améliorer l'adhérence d'un matériau fibreux au caoutchouc dans un composite de caoutchouc, la polyéthylèneimine rendue hydrophobe ayant été rendue hydrophobe pour fournir des substituants qui portent un ou plusieurs groupement(s) réactif(s) pendant(s). L'invention concerne en outre un procédé pour améliorer l'adhérence du matériau fibreux au caoutchouc dans un composite de caoutchouc ; un matériau fibreux enrobé comprenant une polyéthylèneimine rendue hydrophobe enrobée ; un composite de caoutchouc comprenant du caoutchouc et un matériau fibreux, le matériau fibreux ayant un enrobage de polyéthylèneimine rendue hydrophobe ; des procédés de production du matériau fibreux enrobé et de production du composite de caoutchouc ; et une formulation aqueuse, appropriée en tant que solution de trempage, utilisée pour améliorer l'adhérence du matériau fibreux à un caoutchouc dans un composite de caoutchouc.
