摘要：
The object is to provide a viscosity index improver composition which has an excellent viscosity index improving effect. The above problems was solved by a viscosity index improver composition which contains the following poly(meth)acrylate (A) and the following poly(meth)acrylate (B), and satisfies the specific requirement. Poly(meth)acrylate (A): containing a constituent unit (Y) derived from a monomer (y) having a diol functional group, Poly(meth)acrylate (B): containing a constituent unit (Z) derived from a monomer (z) having a boronic acid ester.
