    Abstract: In prodn. of hydrocarbons and hydrocarbon polymers of formula R-C(CH3)2-CH-2-C(CH3)2 -CH2-CH = CH-CH2-Cl (I) where R = a hydrocarbon gp., a tert. C-bonded Cl-contg. component of formula R-C(CH3)2-CH2-C(CH3)2-Cl (II) is reacted with 1-10 mol. butadiene in the presence of a Friedel-Crafts catalyst in a solvent inert to the catalyst. Molecules are obtd. with reactive end gps. which may be further reacted giving a high degree of functionality. The starting material is pref. an oligomer or polymer of isobutene which is obtd. by cationic polymerisation and which contains on one or all chain ends Cl atoms bonded to tert. C-atoms. The solvent is pref. dichloromethane. 1-10 mole BC13 as a Friedel-Crafts catalyst is used per mole Cl-contg. end gps., and work is carried out at a temp. below O deg.C. The catalyst and/or the solvent are distilled off after the reaction and recycled. Polyisobutylenes of general formula CH2-CH = CH2;R1 are claimed, where R1 = Cl or a gp. obtd. by reaction of the cpd. of formula (I) with ammonia, prim. or sec. amine or polyamine, aminoalcohol, aminoether, hydrazine or a hydrazine substd. upto three-fold.

    Abstract: A transparent moulding composition containing (i) an anionically-polymerised star block copolymer of structure (A)m-X where A = a segment of total molecular weight 5000-300000 containing polystyrene (molecular weight 3000-230000) and polybutadiene (molecular weight 2000-30000) blocks with sharp or indistinct block transitions; m = 3-15; and X = residue of an m-functional coupler; and/or (ii) a linear block copolymer with at least 2 polystyrene and at least 1 polybutadiene block of molecular weight values as given above is stabilised against light-, atmospheric oxygen- and/or light-induced degradation by the presence (based on the block copolymer weight) of (a) 0.01-1% alpha-tocopherol; (b) 0.1-2% organic phosphite RO3P where R = alkyl, aryl or cycloalkyl; and preferably also (c) 0.01-0.1% food-grade light stabiliser. Preferably, the compositions contain block copolymers of structure (A)n-X -(B)p. A has total molecular weight 5000-250000; B is a segment of total molecular weight 5000-75000 with at least 1 polystyrene block (molecular weight 2000-60000) and at least 1 polybutadiene block (molecular weight 2000-30000), the block transition being sharp or indistinct; n + p = 3-15; and X = residue of an n + p-functional coupler, with the provisos that n is at most p and at least 1 polystyrene block in A has at least 1.5 times the molecular weight of at least 1 polystyrene block in segment B.

    Abstract: A process for the preparation of telechels by reacting preferably polyfunctional "living" polymers obtained by anionic polymerisation with a functionalising agent, characterised in that the reaction is carried out with stirring with a stirrer having knife-like blades as stirring elements, where the stirring elements are inclined with respect to their plane of motion and essentially pass over the entire space occupied by the reaction mixture.

    Abstract: Impact-resistant thermoplastic moulding compounds containing in relation to the mixture of A, B1 and B2, A: 40 to 94 wt.% of a hard matrix A made up of, in relation to the hard matrix A, 60 to 100 wt.% of units of one or more vinyl aromatic monomers and 0 to 40 wt.% of units of one or more polar comonomers; and B1: 1 to 30 wt.% of a particulate rubber B1 based on a possibly grafted and hydrogenated conjugated polydiene or a block copolymer of a diene and a vinyl aromat (b1) which includes (occludes) components of the hard matrix A, in that is has a capsule, cell or labyrinth particle morphology; B2: 5 to 30 wt.% of a particulate rubber B2 at least partially incompatible with rubber B1, based on a block copolymer b2 of a conjugated diene and a vinyl aromatic compound, possibly grafted with one or more vinyl aromatic monomers and possibly polar comonomers, in which the block copolymer b2 contains at least one block of statically distributed diene and a vinyl aromatic compound, and rubber B2 had a strip morphology; and their use for producing foils, plates or mouldings.
