Abstract

Polymeric, unquaternized or quaternized condensates which contain piperazine rings bonded via chain members are used as conditioners for the pretreatment of nonmetallic surfaces of moldings before their activation for subsequent chemical metallization. This procedure gives particularly uniform and well adhering metal coatings.
