    Abstract: The novel alkadiene/vinyl-aromatic copolymers which contain side groups and have a random, block-like or star-like structure and whose polymerized alkadiene comonomer units are partially or completely selectively hydrogenated, and which contain one or more side groups having one or more radicals capable of (4+2) cycloaddition (Diels-Alder reaction) with dienophiles are suitable as such as viscosity index (VI) improvers or can be used for the preparation of dispersant VI improvers. For this purpose, they are reacted with one or more dienophiles which are capable of a Diels-Alder (4+2) cycloaddition reaction and preferably contain strongly polar functional groups. The resulting selectively hydrogenated alkadiene/vinylaromatic copolymers having one or more side groups which constitute a (4+2) cycloadduct or a Diels-Alder adduct can be modified in their performance characteristics by further reaction with ammonia, an organic amine, an alkylene oxide, a polyalkylene oxide and/or a condensate of ammonia and/or an organic amine with an alkylene oxide.

    Abstract: A process for preparing isobutene homo- or copolymer derivatives by (i) polymerizing isobutene or an isobutene-comprising monomer mixture in the presence of an iron halide-donor complex, an aluminum trihalide-donor complex, or an alkylaluminum halide-donor complex, (ii) reacting a resulting high-reactivity isobutene polymer with a compound which introduces a low molecular weight polar group or a substructure thereof, and (iii) in the case of reaction with a substructure, further reacting to complete the formation of the low molecular weight polar group. The homo- or copolymer derivatives include a radical of a hydrophobic polyisobutene polymer having a number-average molecular weight of 110 to 250,000 and low molecular weight polar groups including amino functions, nitro groups, hydroxyl groups, mercaptan groups, carboxylic acid or carboxylic acid derivative functions, sulfonic acid or sulfonic acid derivative functions, aldehyde functions and/or silyl groups.
