摘要： There is provided a liquid oxidatively modified ethylenic random copolymer, which is an oxidatively modified product of a liquid ethylenic random copolymer comprising 20 to 80 mol % of ethylene and 80 to 20 mol % of .alpha.-olefin, and has (i) a number average molecular weight (Mn) in the range of from 200 to 10,000, (ii) a molecular weight distribution (Mw/Mn) given as weight average molecular weight (Mw) divided by number average molecular weight (Mn) in the range of up to 4, and (iii) an oxygen content of from 0.1 to 20% by weight, an acid value of from 0.1 to 50, and a saponification value of from 0.1 to 100. It is prepared by contacting a corresponding ethylenic random copolymer with oxygen-containing gas at 100.degree.-250.degree. C.
