Title (EN) RESIN USE FOR TACKIFICATION
(FR) RESINE A PROPRIETES TACKIFIANTES
Abstract:
(EN) The invention concerns formulations for hot melt pressure sensitive adhesives. The formulation includes an adhesive formulation for hot melt pressure sensitive adhesives including a styrene-butadiene block copolymer and a petroleum resin produced by copolymerising using a Friedel Craft catalyst, a mixture of (1) from 40 to 90 wt % of a feed comprising C5 olefins and/or diolefins, and/or C6 olefins and/or diolefins; (2) from 10 to 50 wt % of a feed comprising C8-C10 aromatic compounds the wt % being calculated on the basis of the total weight of polymerisable feed components. The resin should possess (a) a level of aromaticity of from 13 to 45 wt % as determined by proton NMR, (b) a softening point of from 50 to 100 °C, (c) an Mn of from 400 to 900 and an Mz of below 2200 and Mw below 1300 and a ratio of Mw/Mn of from 1.2 to 1.7
(FR) L'invention concerne des formulations pour adhésifs sensibles à la thermofusion. Il s'agit d'une formulation pour les adhésifs sensibles à la thermofusion composés d'un copolymère bloc styrène-butadiène et d'une résine de pétrole produite par copolymérisation en utilisant un catalyseur de Friedel-Craft, soit un mélange de (1) 40 à 90 % en poids d'un produit de départ comprenant des oléfines et/ou des dioléines C5 et/ou des oléfines et/ou des dioléfines C6; (2) 10 à 50 % en poids d'un produit de départ comprenant des séries aromatiques C8-C10 dont le pourcentage en poids est calculé sur la base du poids total des éléments d'alimentation polymérisables. La résine possédera : (a) un niveau d'aromaticité de 13 à 45 % en poids, déterminé par la RMN protonique, (b) un point de ramollissement situé entre 50 et 100°C, (c) un Mn de 400 à 900, un Mz inférieur à 2200, un Mw inférieur à 1300 et un rapport Mw/Mn situé entre 1.2 et 1.7.
