20090286914 | SEMI-CRYSTALLINE POLYMER COMPOSITION AND ARTICLE MANUFACTURED THEREFROM - Polymer composition comprising (i) at least one semi-crystalline polymer (SCP) chosen from polyamides, polyaryletherketones, liquid crystal polymers, polyalkylene phthalates, polycarbonates, polyarylene sulphides and polyarylene oxides, and (ii) at least one oxide (OX) chosen from acid oxides of an element having an electronegativity of at most 2.2 and amphoteric oxides, and (iii) at least one nitride (NJ) of an element having an electronegativity of from 1.3 to 2.5. Article comprising at least one part comprising the polymer composition as above described. Part of an article comprising the polymer composition as above described. | 11-19-2009 |
20110204407 | Power LED device with a reflector made of aromatic polyester and/or wholly aromatic polyester - A Power LED device including a reflector and a light emitting diode (LED). The reflector is made of aromatic polyester and/or wholly aromatic polyester. | 08-25-2011 |
20110213077 | Hydroquinone-containing polyesters having improved whiteness - A polyester containing polymerized units of hydroquinone; 4,4′-biphenol; and hydroxybenzoic acid; terephthalic acid and optionally isophthalic acid. A method of forming a polyester including first acylating a mixture of hydroquinone; 4,4′-biphenol; terephthalic acid and optionally isophthalic acid; and hydroxybenzoic acid; and then polycondensing the resulting acylated mixture. The polyester is suitable for uses such as lighting where high whiteness, high reflectivity and high heat resistance are desirable. | 09-01-2011 |
20120029124 | Halogen Free Flame Retardant Polyamide Composition - A polymer composition comprising (i) at least one semi-aromatic polyamide having a melting point of at least 270° C., (ii) at least one organophosphorous compound selected from phosphinates, diphosphinates and condensation products thereof, and (iii) at least 0.01 wt. %, based on the total weight of the composition, of calcium oxide. | 02-02-2012 |

20090318589 | Additive composition for mortars, cements and joint compounds and cementitious compositions made therefrom - An additive composition for mortars, exterior insulation finish systems, self-leveling compounds and joint compounds is disclosed. The additive composition contains a nitrogen-containing polymer and a reactive agent capable of forming a crosslinking reaction with the nitrogen-containing polymer. Small amounts of the additive composition contained in a product cannot only increase one or more properties of the product but can also minimize the use of redispersible polymers in the product. | 12-24-2009 |
20110159308 | IMPROVED BARRIER LAYER - Disclosed herein is a barrier layer comprising a polyvinyl amine-polyvinyl alcohol copolymer applied to a substrate as a water-soluble composition, wherein the polyvinyl amine-polyvinyl alcohol copolymer is formed by copolymerizing: (a) from 99 to 1 mol % of N-vinylformamide and (b) from 1 to 99 mol % of one or more vinyl Ci-Ci0 alkyl esters, and then hydrolyzing from 30 to 100 mol % of the formyl groups from the copolymerized units (a) to form amino groups and from 30 to 100 mol % of the Cj-Cio alkyl ester groups from the copolymerized units (b) to form hydroxyl groups, wherein the copolymer has a unimodal compositional distribution as evidenced by essentially one peak in a gel permeation gradient elution chromatographic analysis. A method of producing a barrier layer is also disclosed. | 06-30-2011 |
