The present invention concerns a process for preparing continuously variable composition copolymers comprising: (a) providing a reaction vessel comprising a first monomer composition; (b) providing afeed vessel comprising a second monomer composition; (c) initiating a polymerization reaction in said reaction vessel; (d) continuing the polymerization reaction during the gradual addition of said second monomer composition from said feed vessel to said reaction vessel wherein the gradual addition of the second monomer composition is performed such that continuously variable composition copolymers are achieved; (e) maintaining said polymerization until at least 90 % of the total monomer composition has been converted to a copolymer; wherein said copolymer has a weight average molecular weightfrom 10,000 to 1,000,000; said copolymer is soluble in lubricating oil, characterized in that the monomers provided in the reaction vessel by said first monomer composition composes at least 50 % byweight of all the monomers used to prepare said copolymer.
