Abstract

La presente invencion proporciona dispersantes y mejoradores del índice de viscosidad del dispersante que incluye polímeros de dienos conjugados que han sido hidrogenados y funcionalizados. Las sustancias dispersantes incluyen composiciones que incluyen un copolímero de dos diferentes dienos conjugados, un copolímero de p-alquilestireno y un dieno conjugado, o un homopolímero de un dieno conjugado. Los plímeros son hidrogenados selectivamente para producir polímeros que tienen cantidades de insaturacion alatmente controladas, permitiendo una funcionalizacion altamente controlada. También se proporcionan fluidos lubricantes, tales como aceites minerales y sintéticos, que han sido modificados en su dispersancia y/o propiedades viscométricas por medio de las sustancias dispersantes de la invencion. También se proporcionan métodos para la modificacion de la dispersancia y/o las propiedades viscométicas de los fluidos lubricantes, tales como los aceites lubricantes minerales y sintéticos. Las sustancias dispersantes también pueden incluir un fluido portador para proporcionar concentrados del dispersante.
