Patent number: 7084196Abstract: Polymeric substrates, for example polyolefins such as polypropylene, can be made flame retardant by the incorporation therein of a synergistic mixture of (i.) at least one compound selected from the group consisting of nitroxyl stabilizers, hydroxylamine stabilizers, nitrone stabilizers, substituted hydroxylamine stabilizers, amine oxide stabilizers, benzofuranone stabilizers phosphite and phosphonite stabilizers, quinone methide stabilizers and monoacrylate esters of 2,2?-alkylidenebisphenol stabilizers and (ii.) at least one compound selected from the group consisting of brominated flame retardants, phosphorus containing flame retardants and inorganic flame retardants such as ammonium polyphosphate or decabromodiphenyl oxide; wherein the amount of organic or inorganic flame retardant of component (ii.) required to achieve an acceptable level of flame retardancy is significantly reduced compared to that needed when component (i.) is not present.Type: GrantFiled: March 12, 2002Date of Patent: August 1, 2006Assignee: Ciba Specialty Chemicals CorporationInventors: Malisa V. Troutman, Ramanathan Ravichandran, Rangarajan Srinivsan, Roswell Easton King, Douglas Wayn Horsey

Patent number: 6992124Abstract: The present invention relates to a synergistic additives mixture for producing calendered polyolefin articles, comprising A) at least one component from the group of peroxide-destroying phosphorus or sulfur compounds, B) at least one component from the group of phenolic antioxidants, C) at least one component from the group of sterically hindered amines, and D) if desired, further additives. Using this additive mixture prevents sticking to the hot roll surfaces and reduces the degradation of the polymer.Type: GrantFiled: February 3, 1999Date of Patent: January 31, 2006Assignee: Clariant GmbHInventors: Christian Wick, Gerhard Pfahler, Alexander Lichtblau
