| 524128000 | Phosphorus bonded directly to three chalcogen atoms only, e.g., phosphite, etc. | 11 |
| 20100048780 | PREVENTION OF COLOR FORMATION IN POLYOLEFINS - Compositions that have been stabilized to prevent gas fading are disclosed. The compositions comprise a polyolefin, a phenolic antioxidant, and at least of either a phosphite stabilizer or a hydroxyl amine stabilizer. Unlike previous stabilizer systems, which have used “phenolic free” polymers, the inventive stabilizer system can stabilize polyolefins against gas fading in the presence of a phenolic antioxidant. | 02-25-2010 |
| 20100216923 | METHOD FOR REDUCING PLATE-OUT OF SOLID PHOSPHITES IN POLYMERS - A process is described which reduces the amount of bloom and/or plate-out of phosphite antioxidants during polymer processing by the addition of at least one polyethylene glycol (or blends thereof) or polycaprolactones (or blends thereof) having an average molecular weight of approximately 1,000 to 20,000, most preferably between 4,000 to 10,000. | 08-26-2010 |
| 20120129989 | Thermoplastic Resin Composition and Molded Product Using the Same - Provided is a thermoplastic resin composition that includes (A) a base resin including (A-1) a polycarbonate resin and (A-2) a polyester resin, (B) a styrene-based polymer, (C) an impact-reinforcing agent and (D) a phenol-based antioxidant. | 05-24-2012 |
| 20130053489 | POLYETHERIMIDE COMPOSITIONS AND METHODS FOR THE MANUFACTURE AND USE THEREOF - This disclosure relates to polyetherimide compositions whose residual phenolic monomers exhibit little or no estradiol binding activity. Also disclosed are methods for making the disclosed polyetherimides and articles of manufacture comprising the disclosed polyetherimides. | 02-28-2013 |
| 20130165563 | POLYPROPYLENE WITH LOW FLUID RETENTION - A controlled rheology polypropylene that is made from Ziegler-Natta produced random copolymer and an additive formulation, extruded in the presence of a peroxide, exhibits low fluid retention and can be used to make medical/laboratory grade equipment, such a pipette tips. | 06-27-2013 |
| 20130225736 | ALKYLPHENOL FREE - LIQUID POLYMERIC POLYPHOSPHITE POLYMER STABILIZERS - An alkylphenol-free liquid polymeric polyphosphite is described of general Structure IV illustrated below | 08-29-2013 |
| 20130345346 | CYCLOALIPHATIC POLYPHOSPHITE POLYMER STABILIZERS - A polymeric polyphosphite and copolymeric polyphosphite is described which contains a cycloaliphatic moiety, preferably cyclohexane dimethanol, in the polyphosphite backbone chain. | 12-26-2013 |
| 20140296397 | TRANSPARENT THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE PREPARED THEREFROM - Disclosed are a transparent thermoplastic resin composition and a molded article prepared therefrom. More particularly, disclosed are a transparent thermoplastic resin composition comprising A) 100 parts by weight of a rubber-reinforced thermoplastic transparent resin, and B) 0.01 to 2 parts by weight of a dihydrocarbyl pentaerythritol diphosphite wherein the A) rubber-reinforced thermoplastic transparent resin is prepared by polymerizing 5 to 60% by weight of a conjugated diene rubber, 20 to 70% by weight of a methacrylic acid alkyl ester monomer or an acrylic acid alkyl ester monomer, 8 to 50% by weight of an aromatic vinyl monomer and 0 to 20% by weight of a vinyl cyanide monomer, and a molded article prepared therefrom. | 10-02-2014 |
| 20140329943 | ALKYLPHENOL FREE - LIQUID POLYMERIC POLYPHOSPHITE POLYMER STABILIZERS - An alkylphenol-free colorless liquid copolymeric polyphosphite is described of generic formula: | 11-06-2014 |
| 20140378590 | CYCLOALIPHATIC POLYPHOSPHITE - A polymeric polyphosphite and copolymeric polyphosphite is described which contains a cycloaliphatic moiety, preferably cyclohexane dimethanol, in the polyphosphite backbone chain. Incorporation of the polymeric polyphosphite into synthetic polymers reduces the yellowness index of any polymer into which the polymeric polyphosphite additive has been added, as well as increased hydrolytic stability as well as increased resistance to migration in food packaging. | 12-25-2014 |
