The invention relates to a polymer obtainable by the radical polymerization of at least one monomer, namely one or more (meth)acrylate monomers and optionally, in addition, vinylic comonomers, wherein the polymer has a molar mass Mof at least 5,000 g/mol and at most 200,000 g/mol and at least one of the monomers is functionalized with at least one epoxy group, wherein the proportion of the epoxide-functionalized monomer(s) (a) is more than 30 wt %.

Functionalized (co)polymers for adhesive systems

The invention relates to a dispersion comprising one or more protic solvents as dispersion medium and also, as base components dispersed therein,

Curable adhesive compound and reactive adhesive tapes based thereon

The invention relates to a thermally curable adhesive compound consisting of the following components: (A) 4.9 to 34.9 wt % (relative to the total amount of the curable adhesive compound) of an epoxide-functionalized (co)polymer having a weight-average molar mass in the range of 5,000 g/mol to 200,000 g/mol, based on more than 30 to 100 wt %, preferably 50 to 100 wt %, (relative to the total amount of the monomers on which the epoxide-functionalized (co)polymer is based) of at least one type of (meth)acrylic (co)monomer (a) functionalized with an epoxy group, (B) 0.1 to 5 wt % (relative to the total amount of the curable adhesive compound) of at least one thermally activatable curing agent for a cationic curing of epoxides, (C) 65 to 95 wt % (relative to the total amount of the curable adhesive compound) of at least one type of matrix polymer as a film-forming agent, (D) optionally 0 to 30 wt % of additional components.
