The invention relates to a reactive batch of thermoplastic polymer particles on the basis of poly-α-olefins, elastomeric block copolymers and/or polyisobutylenes. Said batch is useful for producing insulating glass units consisting of two or several glass panes, casting resin panes, solar collectors or facade elements for edifices. The reactive batch contains a portion of batch particles which contain polymers with reactive groups selected from hydroxyl groups, amino groups, carboxyl groups, carboxylic acid anhydride groups. mercapto groups, hydrosilicon groups and/or hydrosilyl groups. Another portion of the batch particles contains polymers with reactive groups that are complementary thereto and are selected from isocyanate groups, epoxide groups, active olefinically unsaturated double bonds and/or water-producing substances. Said batch of reactive particles is homogenised only directly before the last use and, immediately afterwards, is applied to the substrate surfaces to be connected. Dosing problems have not been observed with respect to this kind of reactive granulates. |
