20120245269 | Compound for purging residual polyamides from an extruder - A purging compound for purging an extruder of polyamides or other polar thermoplastic resins for transitioning to the extrusion of a non-polar thermoplastic resin, includes a non-polar base polymer compounded with an ethylene-methacrylate copolymer, up to 15% of a mineral, and about 1% of a suitable antioxidant. | 09-27-2012 |
20110277669 | Liquid Compositions Of Polymer Additives And Method For Their Preparation - A method is described for preparing liquid concentrates of additives for incorporation in polymers, particularly polymers prepared in solution or slurry phase polymerization media. Additive concentrates according to the invention are characterized by a finer dispersion than would result from the direct addition of particulate or granular additives to the same liquid solvent. | 11-17-2011 |
20110112207 | FOAMING AGENTS FOR THERMOPLASTIC RESINS AND METHOD OF PREPARING SAME - Ultra-fine sodium bicarbonate powder (mean particle size less than 5 microns) is produced by the mixing and reaction under agitation at control temperatures of solutions of ammonium bicarbonate and sodium chloride. Precipitated sodium bicarbonate is separated by filtration as a slurry which is dried to produce ultra-fine sodium bicarbonate. Ultra-fine sodium bicarbonate produced by this method also exhibits a narrow particle size distribution which is advantageous in blowing agents for thermoplastic resins, to produce a foamed resin with small cells of a narrow size distribution. | 05-12-2011 |
