Abstract:
1. A composition comprising (a) at least one (meth)acrylic ester E obtained by esterification of an alcohol ALC and methacrylic or acrylic acid, said alcohol ALC contains at least 5 carbon atoms; and (b) 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 (c) at least a polymer PL having pending (meth)acrylic groups and which has a molecular weight between 200 and 9000 g/mol; and wherein the polymer PL is wherein n≧0, m≧0 and n+m≧3-50 and 3≧p≧16, wherein the weight ratio RS/E of the rubber block co-polymer RS to the (meth)acrylic ester E is ≧30%, the weight ratio of the rubber block co-polymer RS to the polymer RS/PL is from 1/1.5 to 5/1, and the amount of the rubber block co-polymer RS is 1 to 40% by weight based on the weight of the composition.
