摘要：
A process for the preparation of continuously variable-composition copolymers by effecting gradual changes in monomer composition during the polymerization is disclosed. Poly(meth)acrylate copolymers made by the process of the present invention have improved lubricating oil additive properties, for example, as pour point depressants, when compared to related polymer additives made by conventional means.
