Abstract

A composition [composition (C)] comprising: from 1 to 90% by weight (wt. %) of at least one a polyetherimide polymer; [PEI polymer, herein after]; from 5 to 94 wt. % of at least one polyphenylsulfone polymer, [PPSU polymer, herein after], from 5 to 75% wt. of at least one fibrous reinforcing filler.

First claim

1 - 14 . (canceled)

15 . A composition, composition (C), comprising:
from 1 to 90 wt. % of at least one polyetherimide polymer, PEI polymer, from 5 to 94 wt. % of at least one polyphenylsulfone polymer, PPSU polymer, wherein more than 50% by moles of recurring units of said PPSU polymer are recurring units (R PPSU ) of formula (A):

and
from 5 to 75 wt. % of at least one reinforcing filler, wherein said reinforcing filler is a fibrous filler,

and wherein all % wt. are based on the total weight of the composition (C).

16 . The composition (C) according to claim 15 , wherein the composition (C) comprises a PEI/PPSU polymer in an amount equal to or above 50 wt. %, based on the total weight of the composition (C).

17 . The composition (C) according to claim 15 , wherein more than 50% of the recurring units (R1) of the PEI polymer are recurring units (R1a) selected from the group consisting of those of formula (XXV) in imide form, their corresponding amic acid forms of formulae (XXVI) and (XXVII), and mixtures thereof:

wherein in formulae (XXVI) and (XXVII) the→denotes isomerism so that in any recurring unit the groups to which the arrows point may exist as shown or in an interchanged position.

18 . The composition (C) according to claim 15 , wherein more than 50% of the recurring units (R1) of the polyetherimide polymer are recurring units (R1a-4) selected from the group consisting of those of formula (XXVIII) in imide form, their corresponding amic acid forms of formulae (XXIX) and (XXX), and mixtures thereof:

wherein in formulae (XXIX) and (XXX) the→denotes isomerism so that in any recurring unit the groups to which the arrows point may exist as shown or in an interchanged position.

19 . The composition (C) according to claim 15 , wherein the PEI polymer is present in an amount ranging from 5-95 wt. %, based on the total weight of the PEI polymer and PPSU polymer.

20 . The composition (C) according to claim 15 , wherein the reinforcing filler is present in an amount ranging from 15 to 70 wt. %, based on the total weight of the polymer composition (C).

21 . The composition (C) according to claim 15 , further comprising one or more than one additional ingredient (I) in an amount below 20% weight based on the total weight of polymer composition (C).

22 . A process for manufacturing the polymer composition (C) according to claim 15 , which comprises mixing:
the at least one polyetherimide polymer, PEI polymer; the at least one polyphenylsulfone polymer, PPSU polymer, wherein more than 50% by moles of the recurring units of said PPSU polymer are recurring units ( Rppsu ) of formula (A):

and
the at least one fibrous reinforcing filler.

23 . The process according to claim 22 , wherein the mixing is carried out by dry blending, slurry mixing, solution mixing, melt mixing, or a combination of dry blending and melt mixing.

24 . A method of manufacturing an article, part of an article, or a composite, wherein the method comprises processing the composition of claim 15 to form the article, the part of an article, or the composite.

25 . A composite part comprising the polymer composition (C) according to claim 15 .

26 . An article comprising at least one composite part according to claim 25 .

27 . An article comprising the composition (C) according to claim 15 .

28 . The article according to claim 27 , wherein the article is a plumbing, a medical, a dental, a healthcare, an aircraft interior, a food service, a dairy equipment, a laboratory animal cage, a laboratory equipment, an electronic device, a mobile electronic part, an automotive part, or a pumping part.
