Abstract: The invention relates to impact-resistant polymer moulding compositions based on (A) polyoxymethylenes, (B) thermoplastic polyurethanes and (C) polyalkylene terephthalates and optionally (D) additives, which expediently comprise from 95 to 40 parts by weight of at least one polyoxymethylene homopolymer and/or copolymer (A), from 5 to 60 parts by weight of a mixture of from 60 to 98% by weight of at least one thermoplastic polyurethane (B) and from 2 to 40% by weight of at least one polyalkylene terephthalate (C), where the percentages by weight are based on the total weight of (B) and (C) and the parts by weight of (A) + (B) + (C) add up to 100 parts by weight and from 0 to 60 parts by weight of an additive (D), to a process for their preparation and to their use. In order to prepare the polymer moulding compositions, by the preferred method, components (A) to (C) and, if used, (D) are introduced individually or as mixtures, into an extruder and melted together at temperatures in the range from 150 to 260@C. The polymer moulding compositions are suitable for the production of films, sheeting or mouldings which are used, for example, in the vehicle, electrical appliance and electrical industries.

Abstract: Bifunctional initiators for anionic polymerization are prepared by reacting an alkenylaromatic compound of the general formula I (I) where Ar is aromatic hydrocarbyl which may be substituted by alkyl or another group inert toward organoalkali metal compounds and may contain nitrogen, R1 is linear or branched alkyl, cycloalkyl, alkenyl or aralkyl or from 1 to 22 carbon atoms where at least the carbon adjacent to the double bond is saturated and aliphatic, R2 is hydrogen or is likewise linear or branched alkyl, cycloalkyl, alkenyl or aralkyl or from 1 to 22 carbon atoms where at least the carbon adjacent to the double bond is saturated and aliphatic, and where R1 and R2 may be part of a common cycloaliphatic ring, in the presence of one or more ethers and of tertiary amines and in the presence or absence of a further inert aliphatic, alicyclic or aromatic solvent, at from -20 DEG to +70 DEG C. with preferably lithium and with dimerization, with the use in addition of poly-cyclic aromatic hydrocarbons which catalytically promote the dimerization in amount of from 0.001 to 50, preferably 20, mol % and with or without the removal of the ethers and/or tertiary amines after the preparation, and are used for polymerizing anionically polymerizable monomers such as styrene.

Abstract: The use of polymer mixt. (I) for the prodn. of moulded prods. which are inscribed with the aid of high-energy radiation is claimed. (I) contains (A) 40-99 wt.% polyoxymethylene homo- or co-polymer, (B) 1-30 wt.% polycarbonate, (C) 0-50 wt.% impact-modifying polymer and (D) 0-50 wt.% fibrous and/or particulate fillers. The prodn. of moulded prods. with markings, comprises exposing a moulded prod. made from (I) to high-energy radiation. Also claimed are moulde prods. with markings obtd. by this process. The markings are made with laser radiation pref. using a Nd/YAG laser. USE/ADVANTAGE - The polyoxymethylene-based mouldings have a good surface structure and good contrast between markings and background.

Abstract: Oligomeric polyfunctional initiators for anionic polymerization of dienes and/or alkenylaromatics are prepared by a process in which a mixture of dialkenylaromatics and alkenylaromatics in a molar ratio of from 1:4 to 1:100, in an inert solvent, is run, at from 25 DEG to 100 DEG C., continuously or in small portions, with thorough mixing, into an initially taken mixture which contains from 1.2 to 3.0 molar equivalents, based on the dialkenylaromatics, of one or more organolithium compounds and an inert solvent, and is polymerized completely. The resulting oligomeric initiators are used for the preparation of unfunctionalized or functionalized polymers or block copolymers from dienes and/or alkenylaromatics, and the functionalized polymers thus prepared are used as prepolymers for other resins.
