Patent number: 8206834Abstract: Multilayer structure comprising at least one couple (L1-L2) of adjacent layers (L1) and (L2), wherein: the layer (L1) comprises at least one polymer composition (C1) comprising: (i) at least one semi-aromatic polyamide, and (ii) at least one impact modifier (I1); the layer (L2) comprises at least one polymer composition (C2) comprising: (i) at least one un-functionalized polyolefin (PO2); (ii) at least one functionalized polyolefin (FPO2), the functionalized polyolefin comprising functional groups chosen from carboxylic groups, their esters, their anhydrides and their salts. Process for manufacturing such multilayer structure, which comprises co-extruding or co-blowmolding polymer compositions (C1) and (C2) so as to obtain one couple (L1-L2) of adjacent layers (L1) and (L2). Shaped article comprising such multilayer structure and process for manufacturing the shaped article.Type: GrantFiled: April 13, 2007Date of Patent: June 26, 2012Assignee: Solvay Advanced Polymers, L.L.C.Inventors: James K.

Patent number: 8008408Abstract: Aromatic polyimide composition and articles manufactured therefrom. This invention relates to an aromatic polyimide molding composition, comprising at least one aromatic polyimide (A) chosen from the group consisting of aromatic polyamide-imide, aromatic polyesterimides and aromatic polyimide free of any ester and amide group of specific type and typically from 0.5 to 30% wt of at least one fluoroelastomer (B), with respect to the total weight of (A) and (B), to a method for manufacturing the same, to a molding process of the same, and to the articles manufactured therefrom. Preferably, the component (A) of the composition is at least one aromatic polyamide-imide manufactured by a process including the polycondensation reaction between (i) at least one acid monomer chosen from trimellitic anhydride and trimellitic anhydride monoacid halides and (ii) at least one commoner chosen from the group consisting of 4,4?-diaminodiphenylmethane, 4,4?-diaminodiphenylether, m-phenylenediamine and mixtures therefrom.Type: GrantFiled: April 26, 2005Date of Patent: August 30, 2011Assignee: SOLVAY (Société Anonyme)Inventors: Gregory Warkoski, Philip Schild, Romano Empaynado, Brian A.
