PROCESS FOR PREPARING LUBRICATING COMPOSITIONS |
摘要 |
The present invention provides a process for preparing a polymer, employing the steps of: (1) contacting a free radical initiator; a chain transfer agent containing a thiocarbonyl thio group and a free radical leaving group; and radically polymerisable monomers, to form a polymer chain; and (2) contacting the polymer chain of step (1) with at least one of a polyvalent coupling agent, a polymerisation inhibitor, a grafting acylating agent, an amine and an oil of lubricating viscosity. The invention further provides compositions. |
