Patent ID: 7687573

Claim:
A water dispersible polyolefin resin composition comprising: a combination of 5 to 70% by mass of (A) a poly(1-butene) resin having (i) a mesopentad fraction [mmmm] of 20 to 80 mole % and (ii) a weight average molecular weight (Mw) measured by gel permeation chromatography (GPC) of 10,000 to 1,000,000, with 95 to 30% by mass of (B) water; (C) a surfactant in an amount of 0.01 to 1.00 part by mass per 100 parts by mass of said combination, (D) a water-soluble polymeric compound in an amount of 0.01 to 1.00 part by mass per 100 parts by mass of said combination; and (E) a water-insoluble organic solvent in an amount of 2 to 200 parts by mass per 100 parts by mass of said combination; wherein the poly(1-butene) resin is a 1-butene homopolymer or a 1-butene copolymer of 1-butene with at least one of ethylene and a C 3-20 α-olefin other than 1-butene, said copolymer having at least 90 mol % of structural units derived from 1-butene.
