Abstract
An object is to provide a wax dispersant capable of improving the resin composition in the fluidity in a molten state, the transparency and the storage stability, when adding the wax to a thermoplastic resin. The wax dispersant is a copolymer (A) which has a copolymerization composition comprising structural units respectively derived from: an aromatic monomer (A1) within 40 to 94% by mass; a (meth)acrylic acid long chain alkyl ester (A2) represented by the formula (1) (an alcohol residue Ris C9 to C22 alkyl) within 5 to 40% by mass; and a (meth)acrylic acid alkyl ester (A3) represented by the formula (2) (an alcohol residue Ris C1 to C8 alkyl) within 1 to 20% by mass, and also has a weight average molecular weight within 3,000 to 50,000.
