Abstract (en)

[origin: DE19847844A1] Material consisting of a partly crystalline polymer with a dispersed phase comprising solid inorganic particles with a number-weighted average size of less than 100 nm in at least one selected direction for each particle. Independent claims are also included for: (a) molded products, parts of which at least contain material as defined or a mixture containing this material; (b) film with at least one layer containing this material or a mixture thereof; (c) a process for the production of this material by (1) melting the polymer containing the inorganic particles in an extruder and (2) crystallizing from the melt at 30-40 deg C/minute; (d) material obtained by this process.
