Abstract
The low-temperature fluidity improver comprising PA0 (A) an adduct formed by adding a reaction product having the weight average polymerization degree of 1 to 100, which is prepared from an .alpha.-olefin having the average carbon atom number of 10 to 30 and maleic anhydride, to an aliphatic alcohol having the average carbon atom number of 6 to 28, in which the sum of the average carbon atom number in the longest alkyl group chain of the .alpha.-olefin and the average carbon atom number in the longest carbon chain of the aliphatic alcohol is 22 to 40, and/or a salt of said adduct, and PA0 (B) a low molecular weight polyethylene having the numerical average molecular weight of 500 to 20,000 and/or a reaction product thereof with maleic anhydride.
