    Abstract: The invention relates to a process for preparing polyisobutene having a mean molecular weight Mn of from 400 to 50 000, in particular from 500 to 10 000, by polymerizing isobutene in the presence of a BF3-containing complex catalyst, wherein the polymerization is carried out at least temporarily in the presence of one or more cyclic ethers.

    Abstract: Polyisobutenylphenols are prepared by alkylating an aromatic hydroxy compound with substantially monoethylenically unsaturated and substantially homopolymeric polyisobutenes in the presence of a Lewis acid alkylation catalyst by a process in which the polyisobutenes have a beta double bond content of at least 35 mol %.

    Abstract: The use of polycyclic phenolic compounds which have up to 20 benzene rings per molecule and are obtainable by reacting a tetrahydrobenzoxazine I where R1 is a hydrocarbyl radical and R2, R3, R4 and R5 are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals with one or more of the same or different phenols II where R7, R8, R9 and R10 are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals, and/or with one or more of the same or different tetrahydrobenzoxazines I, with the proviso that at least one of the substituents has from 13 to 3000 carbon atoms and the remaining substituents, when they are hydrocarbyl radicals, have in each case from 1 to 20 carbon atoms as stabilizers for stabilizing inanimate organic material against the action of light, oxygen and heat.
