20080227921 | THIN WALLED POLYNITRILE OXIDE CROSSLINKED RUBBER FILM PRODUCTS AND METHODS OF MANUFACTURE THEREOF - Natural rubber and/or synthetic polyisoprene film products having enhanced tear strength and tensile strength crosslinked with a one polynitrile oxide, intended for direct or indirect contact with living tissue or fluids to be placed in living organisms. | 09-18-2008 |
20090209709 | Rubber composition for tire comprising an organosiloxane coupling agent - A subject-matter of the present invention is a rubber composition intended for the manufacture of tyres or of tyre semi-finished products, based on at least one isoprene elastomer, an inorganic filler as reinforcing filler and a polyfunctional organosiloxane coupling agent capable of providing the bonding between the reinforcing inorganic filler and the isoprene elastomer, comprising per molecule, grafted to its silicon atoms, on the one hand at least one hydroxyl or hydrolysable functional group allowing it to be grafted to the reinforcing inorganic filler and, on the other hand, at least one group bearing at least one azodicarbonyl functional group —CO—N═N—CO— allowing it to be grafted to the isoprene elastomer. | 08-20-2009 |
20100113705 | DUAL VESSEL REACTOR - A dual vessel reactor and a method of carrying out a reaction using a dual vessel reactor are provided using a non-condensable gas to substantially isolate the inner vessel from the outer vessel during the reaction and limit the heating of the outer vessel when steam from the inner vessel condenses on the interior surface of the outer vessel. By limiting the heating of the outer vessel through the condensation of the steam or other vapour from the inner vessel, the operating temperature of the outer vessel is kept below an upper threshold of the operating temperature of a seal used to seal the door in the outer vessel. | 05-06-2010 |
