Abstract:
An aqueous dispersion containing a graft copolymer satisfying (a) to (e) and water: (a) a graft rate is 1 to 150% by mass, (b) a weight average molecular weight is 500 to 400000, (c) a molecular weight distribution is 1.5 to 4, (d) a main chain containing a monomer unit having a hydrophilic group and (e) an α-olefin homopolymerization or α-olefin/ethylene copolymerization side chain, wherein a mesopentad ratio [mmmm] of the polymerization chain is 30 to 80 mole %.
