Abstract

The present invention relates to a polymer comprising a polyacrylate homo-or co-polymer backbone incorporating at least one benzylic derivative which is covalently bonded to at least one end of the homo-or co-polymer backbone and its use as a flow and levelling agent, additive, dispersant etc.

Description

[0001] field of invention [0002] The present invention relates to a polymer comprising a polyacrylate homopolymer or copolymer backbone incorporating at least one benzyl derivative bonded to at least one end of the homopolymer or copolymer backbone, And its use as leveling agent, additive, dispersant, etc. [0003] Background of the invention [0004] Polymeric materials are known that are effective for dispersing pigments in organic solvents or water and are useful for forming pigment dispersions of uniform color that can be used to formulate aqueous and solventborne coating compositions. Such pigment dispersions are widely used, for example, in exterior paints for automobiles and trucks. [0005] EP 2 445 944 A1 discloses a pigment dispersion comprising a graft copolymer obtained from a monomer mixture consisting of a) 2-20% by weight of vinylimidazole monomers; b) 55-85% by weight A macromonomer; and c) an amine-functional monomer or an amide-functional monomer or an amm...
