Abstract

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

First claim

The invention claimed is:

1. A composition, consisting of:
from 1 to 90 wt. % of at least one polyetherimide polymer (PEI polymer),
from 20 to 90 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.

2. The composition according to claim 1 , wherein the total weight of the PEI polymer and the PPSU polymer in the composition is equal to or above 50 wt. %, based on the total weight of the composition.

3. The composition according to claim 1 , wherein more than 50 wt. % of recurring units (R1) of the PEI polymer are recurring units (R1a) selected from the group consisting 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 two groups to which the arrows from the same aromatic ring point may exist as shown or in an interchanged position.

4. The composition according to claim 1 , wherein more than 50 wt. % of 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 two groups to which the arrows from the same aromatic ring point may exist as shown or in an interchanged position.

5. The composition according to claim 1 , wherein the PEI polymer is present in an amount ranging from 5 to 95 wt. %, based on the total weight of the PEI polymer and PPSU polymer.

6. The composition according to claim 1 , wherein the reinforcing filler is present in an amount ranging from 1 to 70 wt. %, based on the total weight of the polymer composition.

7. The composition according to claim 1 , wherein the reinforcing filler is selected from the group consisting of glass fiber, carbon fiber, and combinations thereof.

8. The composition (C) according to claim 1 , wherein the reinforcing filler is a fibrous filler selected from glass fiber having a diameter from 5 μm to 40 μm and a length from 1 mm to 20 mm, or carbon fiber.

9. A process for manufacturing the polymer composition according to claim 1 , which comprises mixing:
from 1 to 90 wt. % of the at least one polyetherimide polymer, (PEI polymer);
from 20 to 90 wt. % of 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 (R PPSU ) of formula (A):

and
from 5 to 75 wt. % of the at least one fibrous reinforcing filler,
wherein all wt. % are based on the total weight of the composition.

10. The process according to claim 9 , wherein the mixing is carried out by dry blending, slurry mixing, solution mixing, melt mixing, or a combination of dry blending and melt mixing.

11. A method of manufacturing an article, part of an article, or a composite, wherein the method comprises processing the composition of claim 1 to form the article, the part of an article, or the composite.

12. A composite part comprising the polymer composition according to claim 1 .

13. An article comprising at least one of the composite part according to claim 12 .

14. An article comprising the composition according to claim 1 .

15. The article according to claim 14 , 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.
