A single-layer or multi-layer, biaxially oriented polyester film is provided bearing on at least one film surface a coating for transparency increase. The film has a particle fraction of not more than 0.5% and the coating is a dried water-based or solvent-based solution and/or dispersion having a dry coat thickness of 60-130 nm. The coating includes at least one acrylic acid-based and/or methacrylic acid-based polymer and at least one alkylphosphonate and/or oligo-alkylphosphonate. The coating has a refractive index n<1.64 and a phosphorus fraction of between 2 and 18%. The inventive film is suitable for producing greenhouse energy-saving sheets, particularly for the growing of plants with exacting light demands such as tomatoes. The film has specific transparency properties, high UV stability and good fire properties. The invention further relates to methods for polyester film production and also to the use thereof in greenhouses.

A process for the manufacture of polycarbonate particles is disclosed herein. The process includes combining a first solution including a polycarbonate and a phosphorus-containing flame retardant or a flame retardant polycarbonate, and an organic solvent with a second solution including a surfactant and an aqueous solvent substantially immiscible with the organic solvent, under conditions of shear and temperature effective to provide an emulsion. At least a portion of the organic solvent is removed from the emulsion to provide an aqueous slurry having a plurality of particles, wherein the particles include the polycarbonate and the phosphorus-containing flame retardant or the flame retardant polycarbonate.
