BLOCK COPOLYMER PREPARED BY CONTROLLED RADICAL POLYMERIZATION AND ITS USE AS FLOW MODIFIER

BLOCK COPOLYMER PREPARED BY CONTROLLED RADICAL POLYMERIZATION AND ITS USE AS FLOW MODIFIER

PROBLEM TO BE SOLVED: To provide a new block copolymer usable as a flow controlling agent in a coating composition. SOLUTION: The block copolymer is provided which comprises: (a) a first block comprising 5-95 wt.% of an at least one first ethylenically unsaturated radically polymerizable monomer con...

Zusammenfassung:PROBLEM TO BE SOLVED: To provide a new block copolymer usable as a flow controlling agent in a coating composition. SOLUTION: The block copolymer is provided which comprises: (a) a first block comprising 5-95 wt.% of an at least one first ethylenically unsaturated radically polymerizable monomer containing no hydroxy functionality and 1-20 wt.% of an at least one hydroxy functional ethylenically unsaturated radically polymerizable monomer residues; and (b) a second block comprising 5-95 wt.% of at least one second ethylenically unsaturated radically polymerizable monomer containing no hydroxy functionality and 1-20 wt.% of an at least one hydroxy functional ethylenically unsaturated radically polymerizable monomer residues.
