Abstract
A functionalised polymer, especially an ashless dispersant or a viscosity index improver dispersant, suitable for use as a lubricating or fuel oil additive, or as an intermediate for use in the manufacture of such an additive, is prepared from reactants in different phases by reacting the reactants in a reaction region defined by adjacent surfaces between which there is relative movement or in a thin film on a surface over which they move.
