Abstract

A polymer composition that contains at least one high performance polymer and at least one aromatic amide oligomer is provided. The oligomer can serve as a flow aid that lowers the overall viscosity of the polymer matrix under shear.

First claim

What is claimed is:

1. A polymer composition comprising a high performance polymer having a glass transition temperature of about 100° C. or more and an aromatic amide oligomer having the following general formula (I):

wherein,
ring B is a 6-membered aromatic ring wherein 1 to 3 ring carbon atoms are optionally replaced by nitrogen or oxygen, wherein each nitrogen is optionally oxidized, and wherein ring B may be optionally fused or linked to a 5- or 6-membered aryl, heteroaryl, cycloalkyl, or heterocyclyl;
R 5 is halo, haloalkyl, alkyl, alkenyl, aryl, heteroaryl, cycloalkyl, or heterocyclyl;
m is from 0 to 4;
X 1 and X 2 are independently C(O)HN or NHC(O); and
R 1 and R 2 are independently selected from aryl, heteroaryl, cycloalkyl, and heterocyclyl,
wherein the high performance polymer is a polyetherimide.

2. The polymer composition of claim 1 , wherein the aromatic amide oligomer has a molecular weight of about 2,000 grams per mole or less.

3. The polymer composition of claim 1 , wherein ring B is phenyl.

4. The polymer composition of claim 1 , wherein the aromatic amide oligomer has the following general formula (II):

wherein,
X 1 and X 2 are independently C(O)HN or NHC(O);
R 5 , R 8 , and R 9 are independently selected from halo, haloalkyl, alkyl, alkenyl, alkynyl, aryl, heteroaryl, cycloalkyl, and heterocyclyl;
m is from 0 to 4; and
q and r are independently from 0 to 5.

5. The polymer composition of claim 4 , wherein m, q, and r are 0.

6. The polymer composition of claim 4 , wherein R 8 and R 9 are phenyl substituted with —C(O)HN— or —NHC(O)—.

7. The polymer composition of claim 1 , wherein the oligomer is selected from the group consisting of the following compounds and combinations thereof:
