    摘要： The invention concerns a polyester film with improved abrasion resistance, dimensional stability, drawability and slip properties. The film is characterized by the fact that it contains 0.005 to 5.0% by weight of organic, preferably hardened or crosslinked, particles with narrow particle size distribution in a range between 0.01 and 5 microns, as well as a nucleating agent in an amount from 0.01 to 10% by weight, both values related to the weight of the polymers which form the film.

    摘要： An abrasion-resistant, multilayer biaxially oriented carrier film for magnetic information media is described, composed of a base layer (A) comprising a thermoplastic polymer matrix of essentially linear aromatic polyester, containing finely distributed solid particles to improve the surface roughness which determines the slip properties of the film, and of at least one homopolyester cover layer (B) applied to one of the two surfaces of base layer (A). The characterizing features of the carrier film described lie in the fact that base layer (A) contains solid particles in 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 0.3 to 20 microns, by the fact that cover layer (B) comprises a thermoplastic polymer matrix of essentially linear aromatic homopolyester, in which finely distributed solid particles in an amount from 0 to 10 wt. % based on the weight of the polymer forming cover layer (B) are embedded, 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).

    摘要： A process is described for the production of an oriented, heat-set polyester film including an admixture of polydiorganosiloxane in the amount of 0.001 to 2% by weight, as well as further additives, such as inert inorganic and/or organic particles. The thermoplastic material is melted in an extruder and extruded through an appropriate die to give a cast film, is then quenched, reheated, stretch oriented, and heat set. The characteristic criteria is the addition of the polydiorganosiloxane to the polydiorganosiloxane-free polyester in the form of a masterbatch.
