Particulate Carbonates And Their Preparation And Use In Thermoplastic Film Compositions
A method of producing a breathable film which comprises the steps of: (a) producing an inorganic filler by treating particles of an inorganic particulate material comprising an alkaline earth metal carbonate compound by reaction with a hydrophobising surface treatment agent comprising one or more aliphatic carboxylic acids having at least 10 chain carbon atoms to produce a hydrophobic coating on the particles under conditions such that the inorganic filler produced has a total surface moisture level comprising moisture adsorbed on the particles and trapped within the hydrophobic coating thereon of not greater than 0. 1% by weight based on the dry weight of the inorganic particulate material; (b) producing a filled thermoplastic composition by mixing the inorganic filler produced in step (a) with a heated thermoplastic polymer; and (c) shaping the composition produced in step (b) by heat processing to form a film product.

Abstract:
The present invention is a method of producing a breathable film including producing an inorganic filler by treating particles of an inorganic particulate material comprising an alkaline earth metal carbonate compound by reaction with a hydrophobizing surface treatment agent comprising one or more aliphatic carboxylic acids having at least 10 chain carbon atoms to produce a hydrophobic coating on the particles including a classification step to result in an inorganic filler having a reduced level of interfering particles. The invention is also breathable polymeric films made using the novel filler.

Abstract:
A mineral containing thermoplastic granule for incorporation in a thermoplastic material to produce a thermoplastic end product, the granule comprising at least 50% by weight of an inorganic particulate material, at least 0. 1% by weight of an additive comprising a blowing agent, and the balance comprising a thermoplastic binder.
Methods For Preparing And Compositions Including Untreated And Surface-Treated Alkaline Earth Metal Carbonates
Methods for preparing and compositions including untreated and surface-treated alkaline earth metal carbonate particulates are described. For example, a method for processing alkaline earth metal carbonate may include introducing alkaline earth metal carbonate into a stirred media mill, and dry grinding the alkaline earth metal carbonate in the stirred media mill to produce an untreated alkaline earth metal carbonate particulate having certain characteristics. In some examples, the method may include introducing carboxylic acid and/or carboxylic acid salt into the stirred media mill, and dry grinding the alkaline earth metal carbonate and the carboxylic acid and/or carboxylic acid salt in an integrated dry grinding and surface-treating process in the stirred media mill to produce a surface-treated alkaline earth metal carbonate particulate. In some examples, heating may be added during the dry grinding process.
