Title: METHOD FOR WELDING A POLYOLEFIN PLASTIC AND A PLASTIC BASED ON A POLYMER CONTAINING CARBONYL GROUPS
Abstract:
The invention relates to 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 in said primer, at least 20 wt.% of a polymer that comprises maleic anhydride or maleic anhydride derivative units. The invention also relates to correspondingly welded products.
