    摘要: In an aspect, a method of synthesizing a graft copolymer comprises the steps of: copolymerizing a first macromonomer and a first reactive diluent; wherein said first macromonomer comprises a first backbone precursor directly or indirectly covalently linked to a first polymer side chain group; wherein said reactive diluent is provided in the presence of the first macromonomer at an amount selected so as to result in formation said graft copolymer having a first backbone incorporating said diluent and said first macromonomer in a first polymer block characterized by a preselected first graft density or a preselected first graft distribution of said first macromonomer. In some embodiments of this aspect, said preselected first graft density is any value selected from the range of 0.05 to 0.75. In some methods, the composition and amount of said diluent is selected to provide both a first preselected first graft density and a first preselected first graft distribution.

    摘要: Herein disclosed are a novel methacrylic copolymer capable of serving as a component for uniformly dispersing pigments in paints and varnishes and a dispersant comprising the copolymer. The dispersant for dispersing pigments in non-aqueous paints and varnishes comprises a methacrylic copolymer obtained by copolymerizing 10 to 85 parts by weight of at least one (meth)acrylate monomer selected from, for instance, alkyl (meth)acrylates, alkenyl (meth)acrylates, hydroxyalkyl (meth)acrylates and alkylalkenyl monoalkylene glycol (meth)acrylates, 10 to 60 parts by weight of aminoalkyl (meth)acrylate monomer and/or quaternary ammonium (meth)acrylate monomer and 5 to 30 parts by weight of a monomer carrying a terminal (meth)acryloyl group and having an average molecular weight ranging from 4000 to 1000000.
