Abstract:
The disclosed invention relates to lubricant or functional fluid compositions containing viscosity index improvers in the form of self-healing polymers. The polymers may comprise one or more cleavable linkages, such as one or more disulfide bonds and/or one or more diene/dienophile linkages, to permit the polymer to reform if cleaved during use.
