Abstract: The polyester film has improved abrasion resistance, dimensional stability, extensibility and slip properties and is characterised in that it contains from 0.005 to 5.0% by weight of organic, preferably cured or crosslinked particles having a narrow particle size distribution in the range from 0.01 to 5 mu m, and a nucleating agent in an amount from 0.01 to 10% by weight, both values being based on the weight of the polymer forming the film.

Abstract: Polyester film, with improved abrasion resistance, dimensions, stability, elongation at break and slip, contains 0.005-5.0 (wt)% organic particles (I), which pref. are cured, with a narrow particle size distribution in the 0.01-5 micron range and 0.01-10% nucleating agent (II), both w.r.t. the wt. of polymer forming the film. Pref. (I) is based on a melamine-HCHO, benzoguanamine-HCHO, phenol-HCHO, epoxide oracrylate resin, pref. prepd. by suspension of emulsion polymerisation. Pref. (II) is an alkali(ne earth) salt of (partly hydrolysed) ester waxes, e.g. montanic acid, ionic copolymers of ethylene and alkali methacrylates, alkali phenosulphonates and/or inorg. nucleating agents, esp. Na montanate and/or copolymers of ethylene and alkali methacrylates.

Abstract: An abrasion-resistant, multilayer biaxially oriented carrier film for magnetic information media produced by coextrusion is described, said film being composed of a base layer (A) comprising a thermoplastic polymer matrix of essentially linear aromatic polyester, containing finely distributed solid particles to improve its surface roughness which determines the slip properties of the film, and of at least one cover layer (B) applied to one of the two surfaces of base layer (A). The characterizing features of the carrier film described consist in the fact that base layer (A) contains the solid particles in an an amount from 0.001 wt. % to 10 wt. %, based on the weight of the polymer forming base layer (A), whereby the average particle size of the solid particles lies in the range from 0.001 to 20 microns, by the fact that cover layer (B) comprises a thermoplastic polymer matrix of essentially linear aromatic copolyester, in which finely distributed solid particles are embedded in a quantity between 0 and 10 wt. %, based on the weight of the polymer forming cover layer (B), whereby the solid particles have an average particle diameter of less than 0.3 micron, and by the fact that the layer thickness of cover layer (B) is a maximum of 40% of the layer thickness of base layer (A).

Abstract: of the disclosure: Polyolefins having a broad molecular weight distribution are obtained in a very high yield even using, as the catalyst, a product from the reaction of a magnesium alcoholate with titanium tetrachloride, if the reaction between the magnesium alcoholate and the titanium tetrachloride is carried out at a relatively low temperature and the reaction mixture is then heated to a fairly high temperature in order to split of alkyl chlorides.

Abstract: of the disclosure: Polyolefins having a broad molecular weight distribution are obtained in a very high yield even using a catalyst based on a reaction product of a magnesium alcoholate with titanium tetrachloride, if the hydrocarboninsoluble product of the reaction of the magnesium alcoholate with titanium tetrachloride is heated to a fairly high temperature with a chloroalkoxytitanate, in order to split off alkyl chlorides.
