Abstract: A process for the preparation of polyisobutene derivatives involves bringing an oxygen-containing gas in contact with polyisobutene, in the presence of a photosensitizer, and irradiating the reaction mixture. The polyisobutene derivatives are useful, for example, in hydrocarbon mixtures or hydrocarbon-containing oils.

Abstract: A process for the manufacturing of copoly mers of aldehydes, vinyl ethers, and certain copolymers of aldehydes and vinyl ethers can be performed. The copolymerisation is carried out in the presence of at least one reactive boron trihalide complex, and optionally, in the presence of at least one Bronsted Acid and/or Lewis Base.

Abstract: A process stabilizes polyisobutenes by processing the polyisobutenes in at least one kneader or extruder. The polyisobutene contains at least one chromanol as a stabilizer, or the chromanol is incorporated into the polyisobutene. The polyisobutene is added to or forms sealants, adhesives, coatings, roofings, white and black filled sheeting, and chewing gum.
