摘要： 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 MW of 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 %.

摘要： 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.

摘要： The invention relates to a dispersion comprising one or more protic solvents as dispersion medium and also, as base components dispersed therein, one or more matrix polymers, one or more epoxides, at least one kind of a modified compound of the polyamine adduct type which is insoluble in the epoxides, where the at least one modified polyamine adduct is in dispersion in particulate form, with 90% of the particles having a particle size in the range from 0.1 to 10 μm as determined by laser diffractometry.
