Abstract: Process for the copolymerization of free radical polymerizable comonomers such as vinyl acetate with an unsaturated diester such as diakyl fumarate which is carried out in the presence of water to produce copolymers such as fumarate vinyl acetate copolymers useful as lubricating oil and fuel oil additives, for example, as wax crystal modifiers and flow improvers.
