Patent attributes
The present invention relates to (meth)acrylic adhesives with high impact resistance and no or low odor. The compositions comprise at least a (meth)acrylic ester E which may be obtained by esterification of an alcohol ALC and methacrylic or acrylic acid, said alcohol ALC contains at least 5 carbon atoms; and at least a rubber block co-polymer RS being solid at room temperature and which is a co-polymer of styrene and butadiene and/or isoprene and/or ethylene propylene diene monomer; and at least a polymer PL having pending (meth)acrylic groups and is a butadiene/acrylonitrile co-polymer with terminal (meth)acrylic groups or a polyurethane (meth)acrylate or an ester obtainable by esterification of an alcohol ALC-II and methacrylic or acrylic acid and which has a molecular weight between 200 and 9000 g/mol. Such combinations E-RS-PL have lower viscosity than PL and a combination E-RS.
