Abstract: 1. Thermoplastic mouldingmaterials (I) comprise 20-79 pts. wt. polyphenylene ether (PPE), 1-20 pts. wt. A-B-A' block copolymer comprising two vinylaromatic blocks A, A' and a partly hydrogenated rubber block B (II), 0-70 pts.wt. of a polyvinylaromatic (III) and 0-40 pts.wt. usual additives; the novelty is that mol. wts. of A and A' differ by a factor of 2-20, shorter block (A) has mol.wt. 2000-4000 and A+A' constitute 35-50 wt.% of (II). 2. (I) are mfd. by mixing at 250-320 deg.C for 0.5-30 mins. Specifically, A+A' make up 35-40 wt.% of (II), mol. wts. of A and A' differ by a factor of 4-8 and A has mol.wt. 3000-3800; block B still contains 10-20 wt.% of the double bonds originally present.

Abstract: A process for the preparation of copolymers by polymerising from 52 to 54% by weight of styrene and 48 to 46% by weight of butadiene with alkyllithium initiators in the presence of tetrahydrofuran, where certain maximum temperatures are not exceeded, and subsequently hydrogenating the copolymer, and the use of the hydrogenated copolymers as viscosity index improvers for lubricant oils.

Abstract: A hydrogenated star-shaped polymer (I) has (a) a nucleus of a poly(polyalkenyl aromatic coupling agent) (II) and (b) a number of arms consisting of hydrogenated polymer chains comprising cone shaped copolymers of 4-12C conjugated dienes and 8-12 C monoalkenyl aromatics. The hydrogenated polymer chains comprise a multi-block copolymer with at least 2 blocks of the cone shaped copolymer of the diene and monoalkenyl aromatic. Also claimed is a process for the production of (I) by (i) solution polymerisation of a 4-12C conjugated diene and a monoalkenyl aromatic in the presence of an anionic polymerisation initiator to form a living cone shaped copolymer, (ii) reaction of the resulting product with a 10-20C polyalkenyl aromatic coupling agent (II) or a mixture of (II) with a 8-12C alkenyl aromatic to form a star shaped polymer and (iii) deactivation and hydrogenation of the resulting polymer.
