Described are adhesive compositions comprising: (i) at least one reactive monomer (A) selected from ethylenically unsaturated carboxylic acid derivatives and mixtures of such derivatives, said one or more derivatives preferably being one or more esters, (ii) at least one liquid elastomer in a molar weight range of 1000 - 9000 which is functionalized with ethylenically unsaturated groups (B), (iii) at least one impact modifier (C) that is a core shell polymer that does not dissolve but swells in the monomer (i), and (iv) at least one free radical initiator and at least one catalyst, whereby the amount of B referred to the total amount of A+B is 15 to 60 % by weight,and whereby optionally either said initiator, or said catalyst is present separately, in a further component or paste, respectively. Preferably the amount of C referred to the total amount of A+B+C = 5 - 30 % by weight. |
