ABSTRACT:
A liquid modified ethylenic random copolymer selected from an epoxidization product of a liquid ethylenic random copolymer of ethylene and an alpha-olefin having 3 to 20 carbon atoms and a hydroxylation product of a liquid ethylenic random copolymer of ethylene and an alpha-olefin having 3 to 20 carbon atoms. The modified copolymer is characterized in that (i) the liquid modified ethylenic random copolymer has an ethylene component content of 10 to 85 mole % and an alpha-olefin component content of 15 to 90 mole %, (ii) in the .sup.13 C-NMR spectrum of the liquid modified ethylenic random copolymer, signals of .alpha..beta. and .beta..gamma. based on the methylene chain between two adjacent tertiary carbon atoms in the main chain of the copolymer are not observed, (iii) the liquid modified ethylenic random copolymer has a number average molecular weight (Mn), measured by a vapor pressure osmometer, of 200 to 10,000, and (iv) where the liquid modified ethylenic random copolymer is the epoxidized product, each epoxy group therein is positioned at the polymer chain end of the liquid ethylenic random copolymer, and the content of the epoxy groups is 0.01 to 0.5 mole per 100 g of the liquid epoxidized ethylenic random copolymer, and where the liquid modified ethylenic random copolymer is the hydroxylated product, each hydroxyl group therein is bonded to a carbon atom derived from ethylene or the alpha-olefin and positioned at the polymer chain end of the liquid ethylenic random copolymer, and the contents of the hydroxyl groups is 0.01 to 1 mole per 100 g of the liquid hydroxylated ethylenic random copolymer. Also provided are a lubricant oil additive and a paint additive each being composed of the above liquid modified ethylenic random copolymer.
