    Abstract: Expandable polystyrene (EPS) containing blowing agent also contains 0.1-20 wt.% of a blowing aid comprising an oligomeric aliphatic 2-20C olefin (I) and a number average degree of polymerisation (DP) of 2-200, which is liquid at room temperature. Also claimed are methods of producing expandable polystyrene beads.

    Abstract: A process for the production of polymers of 2-12C alkenes at -50 to 300 degrees C and 0.5-3000 bar in presence of a catalyst system, with the addition of a compound of formula H-M )R (I); where M = B, Al, Ga, In or Tl; R , R = H, 1-10C alkyl, 6-15C aryl, or alkaryl or aralkyl with a 1-10C alkyl and a 6-20C aryl group, or 5- to 7-membered cycloalkyl (optionally substituted with 1-10C alkyl); or R + R may form a 4-15C cyclic group. Preferably R and R together form part of a 4-15C bicyclic group; M = boron. The catalyst system contains (A) a metallocene complex and (B) a metallocenium ion-forming compound. A metal compound of formula M )r(R )s(R )t (IV) may also be added; M = alkali or alkaline earth metal, or a Sub-Group III metal, i.e. B, Al, Ga, In or Tl; R = 1-10C alkyl, 6-15C aryl, or alkaryl or aralkyl with 1-10C alkyl and 6-20C aryl groups; R , R = as for R , or also halogen or 1-10C alkoxy; r = 1-3; s, t = 0-2; r + s + t = the valency of M .

    Abstract: Polymers and oligomers of formula (I), based on unsatd. 2-10C hydrocarbons and with one or two 2-oxazolinyl terminal gps., in which A = polymer or oligomer residue derived from the unsatd. hydrocarbon (A'), and R = H, 1-10C alkyl, 6-10C aryl or 3-6C cycloalkyl. Also claimed are (i) comb polymers (II) obtd. by cationic ring-opening homo- or co-polymerisation of (I); (ii) comb polymers (III) obtd. by reacting (I) with base polymers contg. reactive gps.; (iii) thermoplastic moulding materials or thermosets contg. (I), (II) or (III) or mixts. thereof; (iv) a process for the prodn. of (I) by polymerisation or oligomerisation of (A'), modification with one or two terminal ester gps., and Lewis acid-catalysed ring closure with 2-amino-1- alcohols; (v) processes for the prodn. of (II) and (III) under the above conditions; (vi) films, fibres and mouldings obtd. from the materials claimed in (iii).
