|---|
| 20090042006 | Transparent polymer articles of low thickness - The novel transparent polyolefin, polyester or polyamide article disclosed is stabilized against the effects of light, oxygen, heat and aggressive chemicals by addition of 0.005-0.30% by weight the polymeric substrate of a hydroxyphenyl triazine UV absorber, and is characterized by its thickness between 1 and 500 μm. Preferred polyolefin articles thus stabilized are agricultural films containing as further stabilizer a sterically hindered amine. The novel compositions act as selective UV filter especially useful in agriculture. | 02-12-2009 |
| 20090076206 | Additive Mixtures for Agricultural Articles - An agricultural article made of a composition containing (a) an organic polymer, and (b) an additive mixture comprising the components (b-0) a photosensitizer, (b-I) an organic salt of a transition metal, and optionally (b-II) an inorganic peroxide or inorganic superoxide. | 03-19-2009 |
| 20090111917 | Stabilized articles - The present invention relates to non-agricultural articles which keep their properties during the use and degrade later on, until total disintegration and disappearance of the plastic. The invention further relates to a method for controlling the weathering resistance and the degradation of non-agricultural articles. The desired effect is obtained with specific combinations of degradant metal salts and stabilizers. | 04-30-2009 |
| 20090291289 | TRANSPARENT POLYMER ARTICLES OF LOW THICKNESS - The novel transparent polyolefin, polyester or polyamide article disclosed is stabilized against the effects of light, oxygen, heat and agressive chemicals by addition of 0.005-0.30% by weight the polymeric substrate of a hydroxyphenyl triazine UV absorber, and is characterized by its thickness between 1 and 500 μm. Preferred polyolefin articles thus stabilized are agricultural films containing as further stabilizer a sterically hindered amine. The novel compositions act as selective UV filter especially useful in agriculture. | 11-26-2009 |
| 20100048773 | AGRICULTURAL ARTICLES - The present invention relates to agricultural articles which keep their properties during the use and degrade later on, until total disintegration and disappearance of the plastic. The invention further relates to a method for controlling the weathering resistance and the degradation of agricultural articles. The desired effect is obtained with specific combinations of degradant metal salts and stabilizers. | 02-25-2010 |
| 20100178484 | TRANSPARENT POLYMER ARTICLES OF LOW THICKNESS - The novel transparent polyolefin or polyamide article disclosed is stabilized against the effects of light, oxygen, heat and agressive chemicals by addition of 0.005-0.30% by weight the polymeric substrate of a hydroxyphenyl triazine UV absorber, and is characterized by its thickness between 1 and 500 μm. Preferred polyolefin articles thus stabilized are agricultural films containing as further stabilizer a sterically hindered amine. The novel compositions act as selective UV filter especially useful in agriculture. | 07-15-2010 |
| 20100222471 | Stabilizer Composition for Polymers - The invention relates to stabilized thermoplastic polymers, in particular polyolefin films. The stabilizing composition contains a tertiary amine with a molecular weight greater than 400 g/mol, a UV-absorber and/or a sterically hindered amine light stabilizer (HALS). Further aspects of the invention are a process for stabilizing thermoplastic polymers and the use of the above composition for stabilizing thermoplastic polymers. | 09-02-2010 |
| 20110015295 | ADDITIVE MIXTURES FOR AGRICULTURAL ARTICLES - Disclosed are 2,6-bis[octadecyloxy]anthraquinone, 1-(4,6-bis[dibutylamino]-[1,3,5]-triazin-2-ylamino)-anthraquinone, 2-(4,6-bis[dibutylamino]-[1,3,5]-triazin-2-ylaminoyanthraquinone, 2,6-bis[4,6-bis[dibutylamino]-[1,3,5]-triazin-2-yloxy]-anthraquinone, 2-(2-ethyl-hexyloxy)-1-octadecyloxy-anthraquinone, 1,2-bis[octadecyloxy]anthraquinone, 1,2-bis[2-ethyl-hexyloxy]anthraquinone, 1,2-bis[octyloxy]anthraquinone, 1,5-bis[2-ethyl-hexyloxy]anthraquinone, 9,10-dioxo-9,10-dihydro-anthracene-2-sulfonic acid dodecylamide, 2,6-bis[stearoyloxy]anthraquinone and bis[9,10-dioxo-9,10-dihydro-anthracene-2-sulfonic acid]-1′,12′-dodecandiyldiamide. | 01-20-2011 |
| 20110089384 | HIGHLY COMPATIBLE AND NON-MIGRATORY POLYMERIC UV-ABSORBER - The present invention relates to highly compatible hydroxyphenyltriazine UV-absorbers and to their use in organic polymers, especially for protecting the contents of transparent plastic packages such as pharmaceuticals, cosmetics, personal care products, shampoos and the like, and especially foodstuffs such as beverages, fresh vegetables or meat, from the deleterious effects of ultraviolet radiation. Especially advantageous is the combined use of a UV absorber and an oxygen scavenger. It has been found that certain highly compatible tris-aryl-s-triazines are especially effective towards this end when incorporated in the containers or films in which such materials are stored. | 04-21-2011 |
