    Abstract: Ethylenically unsaturated, particularly acrylic, monomers are polymerised using a catalyst system including a manganese carbonyl initiator, an organic halogen reactive substrate and an allylic halide chain termination agent. Desirably the manganese carbonyl initiator is a dimanganese compound, particularly dimanganese decacarbonyl (Mn2(CO)10). The catalysis mechanism appears to involve initiator homolysis, abstraction of halogen from the reactive substrate forming an organic free radical which acts as a chain initiator for polymerisation and eventual reaction of the propagating chain radical with the chain terminating agent. The speed or extent of reaction may be modified by the inclusion of Lewis acids in the reaction mixture. The resulting polymers are telechelic and may have different end groups. The polymers can be reacted further to functionalise them and/or to form block copolymers.

    Abstract: A novel ashless polymeric dispersant is claimed which is suitable for use in an automotive lubricant composition. The ashless polymeric dispersant has a number average molecular weight of between 200 and 15,000 and derived from the reaction of a polar head group, which comprises a polar moiety having more than one amine, alcohol, acid or halogen functionality with two or more polar tail groups where each polar tail group comprises a polymeric backbone of 2 to 30 monomeric repeat units, each repeat unit comprising a hydrocarbon chain functionalised by the presence of at least one electronegative element or moiety. The dispersant has good dispersancy properties, when used as a sole dispersant or in combination with other dispersants. It provides enhanced seal resistance and has good oxidative stability in automotive applications as compared to current commercial products. Furthermore the low temperature viscosity of an automotive lubricant composition containing the dispersant is superior to that of a composition with current commercial dispersants.
