Abstract: Polymers Ia and Ib carrying functional groups, obtainable by A) 1. hydrogenation of the olefinic double bonds of a polymer IIa comprising a) from 20 to 100% by weight of a conjugated diene, b) from 0 to 80% by weight of a vinylaromatic compound and c) from 0 to 20% by weight of further comonomers, to give the hydrogenated polymers IIb, 2. metallation of IIb using an organoalkali metal compound to give IIc, 3. reaction of IIc with a diaziridine III to give IId and 4. hydrolysis or alcoholysis of IId to give Ia, or by B) 1. partial hydrogenation of IIa to give partially hydrogenated polymers IIb', 2. epoxidation of the double bonds of IIb' to give IIe and 3. reaction of IIe with a compound IV carrying functional groups to give Ib. These polymers Ia and Ib are suitable as viscosity index improvers for engine oils.

Abstract: The invention concerns thermoplastic shaping compounds comprising a mixture of anionically polymerized general purpose polystyrene and high-impact polystyrene which is low in monomers, preferably with a weight/mixture ratio of 10: 1 to 1: 10. Each component of the mixture contains fewer than 100 ppm of monomer styrene and, for example, the anionically polymerized general purpose polystyrene has a degree of molecular heterogeneity Mw/Mn of more than 1.5. High-impact polystyrene with an average particle diameter of more than 0.3 mu m is used. The invention further concerns thermoformed packaging for foodstuffs, said packaging being produced using this thermoplastic shaping compound.

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.
