    Abstract: The present invention relates to the use of linear or star-shaped block copolymers which are provided with at least one polymer block A which mainly consists of isobutene units and at least two polymer blocks B which mainly consist of units that are derived from vinyl aromatic monomers. Said block copolymers are used as elastic sealing material. The invention especially relates to the use of such sealing materials for sealing the edge joints in insulating glass panes and insulating glass panes which are provided with a flexible edge-joint sealing which contains one of the block copolymers.

    Abstract: Disclosed is a process for preparing 2-alkylpolyisobutenylphenols and their Mannich adducts, by a) contacting at least one 2-alkylhydroxyaromatic compound of formula (I), wherein R1 is C1-20alkyl, and R2 and alkyl are as defined in the specification, with a catalytically active amount of a BF3 source which is capable of complex formation with the 2-alkylhydroxy compound, and alkylating with substantially monoethylenically unsaturated and substantially homopolymeric polyisobutenes having a number average molecular weight Mn in the range from 150 to 500 000 and comprising at least 50 mol%, based on the total number of polyisobutene macromolecules, of terminal double bonds that may be either vinyl double bonds or vinylidene double bonds, wherein the BF3 source used in step a) is selected from i) gaseous BF3, ii) BF3 complexes with at least one of the 2-alkylhydroxyaromatic compounds used in step a), iii) BF3 complexes with hydroxyaromatic compounds which are substantially not alkylated under the reaction conditions in step a), selected from substituted phenols which have substituents other than hydrogen in the 2-, 4- and 6-position to the OH group and substituted phenols which, in addition to the OH and alkyl group, have at least one further, reactivity-lowering substituent selected from acyl, carboxyl, cyano, nitro and halogen, and iv) mixtures of BF3 with aliphatic alcohols which comprise less than 2 mol of alcohol per mole of BF3, b) if appropriate, subjecting the 2-alkylpolyisobutenylphenols obtained in step a) to an aminoalkylation.

    Abstract: Polynuclear phenolic compounds (Q) with up to 20 benzene nuclei per molecule obtained by the reaction of tetrahydrobenzoxazine compound (I) with one or more phenol compound (II) or one or more another tetrahydrobenzoxazine are used as stabilizers for stabilizing inanimate organic materials against the effects of light, acid and heat. Polynuclear phenolic compounds (Q) with up to 20 benzene nuclei per molecule obtained by the reaction of tetrahydrobenzoxazine compounds of formula (I) with one or more phenol compound of formula (II) or one or more another tetrahydrobenzoxazine are used as stabilizers for stabilizing inanimate organic materials against the effects of light, acid and heat.
