20110152452 | EMULSION POLYMERIZATION PROCESS, POLYMER DISPERSION AND FILM-FORMING COMPOSITION - The present invention relates to a method to prepare a polymer dispersion using an aqueous substantially surfactant-free emulsion polymerization process comprising a seed and a feed stage, in which seed stage at least one ethylenically unsaturated monomer, having a water-solubility of at least 0.3 g/l at polymerization conditions, is polymerized in the presence of an addition fragmentation chain transfer agent and a hydrophilic free radical initiator to form a seed polymer that is substantially insoluble in water and in which feed stage at least one ethylenically unsaturated feed monomer is added to the seed polymer to form polymer particles. With this method a polymer dispersion can be obtained having at least 25 wt. % solid contents in combination with an average polymer particle size smaller than or equal to 300 nm. The invention further relates to a polymer dispersion obtainable by a surfactant-free emulsion polymerization process, a film-forming composition, preferably a coating composition, comprising such a polymer dispersion and coated articles coated with the coating composition. Further, the invention relates to a polymer particle powder obtained from the polymer dispersion and powder coating compositions. | 06-23-2011 |

20140357090 | CYCLIC ALUMINUM NITRIDE DEPOSITION IN A BATCH REACTOR - A process for depositing aluminum nitride is disclosed. The process comprises providing a plurality of semiconductor substrates in a batch process chamber and depositing an aluminum nitride layer on the substrates by performing a plurality of deposition cycles without exposing the substrates to plasma during the deposition cycles. Each deposition cycle comprises flowing an aluminum precursor pulse into the batch process chamber, removing the aluminum precursor from the batch process chamber, and removing the nitrogen precursor from the batch process chamber after flowing the nitrogen precursor and before flowing another pulse of the aluminum precursor. The process chamber may be a hot wall process chamber and the deposition may occur at a deposition pressure of less than 1 Torr. | 12-04-2014 |
