An oil-in-water emulsion of at least one polymer selected from the group consisting of (A) an ethylene-alpha-olefin random copolymer having (1) an ethylene content of 30 to 70 mole%, (2) a number average molecular weight (Mn) of 500 to 10,000, and (3) a weight average molecular weight (Mw) to number average molecular weight (Mn) ratio (Q=Mw/Mn), of 3 at most, and (4) being liquid at ordinary temperatures, and (B) a graft-modified ethylene/alpa-olefin copolymer (1') comprising said ethylene/alpha-olefin copolymer having the characteristics (1) to (4) as a trunk polymer, and (2') at least one grafted unit selected from a unit derived from an unsaturated carboxylic acid or its acid anhydride and a unit resulting from neutralization of at least a part of said unit with an alkali, and (3') being liquid or semisolid at ordinary temperatures. |
