| 1. A graft-modified ethylene (co)polymer (A1-1) produced by graft-modification of an ethylene (co)polymer (A1) with a polar
group-containing monomer, wherein
said ethylene (co)polymer (A1) being either an ethylene homopolymer or a copolymer of ethylene and an α-olefin of 4 to 20
carbon atoms, wherein
(iA1) the ethylene (co)polymer contains methyl branches less than 0.1 in number per 1,000 carbon atoms measured by 13C-NMR, and
(iiA1) the ethylene (co)polymer has a ratio of Mw/Mn (Mw denotes the weight average molecular weight; Mn denotes the number average
molecular weight) measured by gel permeation chromatography is not lower than 1.8 and lower than 4.5.
