  • STABILISATION OF POLYISOBUTENE
    Publication number: 20250043085
    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.

  • COPOLYMERISATION OF ALDEHYDES AND VINYL ETHERS
    Publication number: 20240376245
    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.

  • POLYISOBUTENE DERIVATIVES AS AN ADDITIVE IN RUBBERS
    Publication number: 20240240000
    Abstract: Various polyisobutene derivatives are useful as additives in rubbers, particularly for dispersion and compatibilization of additives in rubbers for vehicle tires, such as carbon black, zinc oxide, and silicates.

  • PROCESS FOR PREPARATION OF POLYISOBUTENE DERIVATIVES
    Publication number: 20230406968
    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.

  • Nitrile rubbers coupled via bisdihydropyrazole groups, production thereof and use thereof
    Publication number: 20140357801
    Abstract: A nitrile rubber coupled via bisdihydropyrazole groups is produced by reacting a nitrile rubber which is based on conjugated dienes, ?,?-unsaturated nitriles and optionally further copolymerizable monomers as monomers, may have been hydrogenated and has covalently bonded tetrazole groups with a bifunctional ene compound in which the ene groups can each be reacted with the tetrazole groups to give dihydropyrazole groups.
