Célene Difrancia

Multilayer structure comprising at least one couple (L-L) of adjacent layers (L) and (L), wherein: Process for manufacturing such multilayer structure, which comprises co-extruding or co-blowmolding polymer compositions (C) and (C) so as to obtain one couple (L-L) of adjacent layers (L) and (L). Shaped article comprising such multilayer structure and process for manufacturing the shaped article.

Multilayer polymer structure

Method for making a hollow body comprising, as sole layer(s), at least one layer L1 consisting of a polyamide composition comprising an aromatic polyamide and an impact modifier, said method comprising extruding the polyamide composition through a die.

Method for making a polyamide hollow body

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&#x2032;-diaminodiphenylether, m-phenylenediamine and mixtures therefrom. Advantageously, the aromatic polyimide composition of the invention, owed to its improved flexibility during the molding process, is suitable for the manufacture of articles from mold of complex geometries, such as undercuts, without permanently deforming or cracking upon ejection from the mold.
