Abstract: Disclosed is a method for welding a polyolefin plastic and a plastic based on at least one polymer containing carbonyl groups, using a primer which contains, in relation to the proportion of polymer, at least 20 wt. % of a polymer that comprises maleic anhydride or maleic anhydride derivative units. Also disclosed are correspondingly welded products.

Abstract: The invention relates to a method for welding a polyolefin plastic and a plastic using a primer, said primer containing at least one maleic anhydride containing polymer and at least one polyester. The invention also relates to correspondingly bonded products.

Abstract: The invention relates to a method for the integral bonding of two workpieces made from different types of thermoplastic polymers with the help of a preferably thermoplastic polymer primer as bonding layer, comprising the following steps: providing a first workpiece made from a thermoplastic polymer having a first edge layer; providing a second workpiece made from a thermoplastic polymer having a second edge layer, said thermoplastic polymer being of a different type to the thermoplastic polymer of the first workpiece; preheating the first edge layer; applying the primer on the preheated first edge layer, wherein, during the application of the primer, the preheated first edge layer has a temperature in the range between the extrapolated onset of the glass transition temperature for amorphous plastics or the peak starting temperature of the melting region for partially crystalline plastics and the step starting temperature of the disintegration of the thermoplastic polymer of the first edge layer; bringing the
