▎ 摘  要

NOVELTY - Polyisobutene derivatives (AI) of (1a)-(6a) are new. USE - (AI) are useful for improving lubricity of hydrocarbon mixtures or hydrocarbon-containing oils, preferably in fuels or lubricants, and gasoline or diesel fuels (claimed). ADVANTAGE - (AI) are improve lubricity of hydrocarbon mixtures or hydrocarbon-containing oils and combustion efficiency of fuel burning devices; are depolymerized so that isobutene or low molecular isobuteneoligomers are released which act beneficially on combustion processes; and exhibit an additional effect in fuels. DETAILED DESCRIPTION - Polyisobutene derivatives (AI) f (1a)-(6a) are new, where (AI) contains at least 5 wt.% derivatives of polyisobutene. n = at least 1, preferably at least 2, preferably at least 8. INDEPENDENT CLAIMS are also included for: (1) mixtures of derivatives of polyisobutene containing at least 5 wt.% of hydroperoxides of polyisobutene (Ia) with polyisobutene and optionally at least one solvent; and (2) preparing mixtures of (AI).
