    摘要: An additive compositon comprising a graft and aminederivatized copolymer prepared from ethylene and at least one (C.sub.3 -C.sub.10) alpha-monoolefin and, optionally, a polyene selected from non-conjugated dienes and trienes comprising from about 15 to 80 mole percent of ethylene, from about 20 to 85 mole percent of said (C.sub.3 -C.sub.10) alpha-monoolefin and from about 0 to 15 mole percent of said polyene, said copolymer having a number average molecular weight ranging from about 5,500 to 50,000 and having grafted thereon at least 1.8 molecules of a carboxylic acid acylating function per molecule of said copolymer and reacting said grafted copolymer with an amino alcohol compound selected from the group consisting of a 2-Anilinoalcohol, a (2-hydroxyalkyl)pyrridine, a 4-(2-hydroxyalkyl) morpholine, a 1-(2-hydroxyalkyl)piperazine, a 1-(2-pyrrolidine and a 1-(2-hydroxyalkyl) 2-pyrrolidine.
