Abstract:
A process for permanently improving surfaces of polyolefin-based moldings and films for bonding with coatings and adhesives, comprising the steps of:(a) molding a composition comprising at least one polyolefin, about 0.01 to about 10% by weight, based on the polyolefin of at least one migratable, crosslinkable amphiphile compound containing at least one substituent of high polarity in an otherwise hydrocarbon-based basic molecule having a molecular weight of about 50 to about 5,000 Dalton and a catalytically effective amount of a catalyst which promotes crosslinking of the crosslinkable amphiphile compound in the plastic surface to form a polyolefin-based molding or film;(b) allowing said crosslinkable amphiphile compound to migrate to the surface of said polyolefin-based molding or film and crosslink.
