Title:
多機能分散剤グラフトポリマー
Document Type and Number:
Japanese Patent JP2008539325
Kind Code:
A
Abstract:
A grafted polymer, either polyolefin or polyester, containing monomers associated with sludge and varnish control as well as monomers associated with soot handling to provide a graft polymer exhibiting multiple performance attributes. Also described are methods for manufacturing these novel multiple-function graft polymers via solution and melt processes. Lubricating oil compositions containing these novel multiple-function polymers as an additive that display performance characteristics directed to good soot handling and sludge and varnish control as well as control of viscosity increase are described.
