Abstract:
1. A waterborne copolymer dispersion comprising 0.1–25% by weight of at least one alkenyl functional dendritic polymer built up from a dendritic core polymer, which core polymer is a hydroxy-functional dendritic polyester, polyether, polyesteramide or polyetheramide and optionally is chain extended, and at least one alkenyl functional compound bonded to said core polymer and/or its optional chain extension, and that said alkenyl functional dendritic polymer is copolymerised to a polymer backbone of at least one homo or copolymer obtainable by polymerisation in an aqueous medium of at least one polymerisable allyl, vinyl, maleic or diene monomer.
