Liquid diene polymers and copolymers terminated by reaction with fused-ring polynuclear aromatic compounds

摘要

A terminally functionalized liquid polymer is prepared by reacting a low molecular weight living diene polymer or copolymer obtained by anionic polymerization of a diene monomer or mixture of a diene monomer and a vinyl aromatic hydrocarbon monomer with a fused-ring polynuclear aromatic compound. The resultant terminally functionalized liquid diene polymers or copolymers can be utilized as dispersants for particulates such as carbon black or graphite and may also be employed as viscosity modifiers for lubricating oils or in electrorheological devices or damping devices.
