Abstract

A thermoplastic composition includes a poly(phenylene ether), a poly(amide), a poly(etherimide), and a reinforcing filler, wherein the specific amount of each component is specified herein. The thermoplastic composition can advantageously exhibit improved physical properties. The thermoplastic composition can be used to form various articles. A method of the manufacture of the composition is also described herein.

Claims (30)

1 . A thermoplastic composition comprising,

10 to 35 weight percent of a poly(phenylene ether);

10 to 55 weight percent of a poly(amide);

1 to 10 weight percent of a poly(etherimide); and

greater than 20 to 60 weight percent of a reinforcing fiber;

wherein the amount of each component is based on the total weight of the thermoplastic composition.

2 . The thermoplastic composition of claim 1 , wherein the poly(phenylene ether) comprises a poly(2,6-dimethyl-1,4-phenylene ether) having an intrinsic viscosity if 0.3 to 0.6 deciliters per gram, measured at 25° C. in chloroform using an Ubbelohde viscometer.

3 . The thermoplastic composition of claim 1 , wherein the poly(phenylene ether) comprises a poly(phenylene ether)-poly(siloxane) block copolymer reaction product comprising a poly(phenylene ether)-poly(siloxane) block copolymer and a second poly(phenylene ether) having an intrinsic viscosity if 0.3 to 0.6 deciliters per gram, measured at 25° C. in chloroform using an Ubbelohde viscometer.

4 . The thermoplastic composition of claim 1 , wherein the poly(amide) comprises nylon-6, nylon-66, a poly(phthalamide), or a combination thereof.

5 . The thermoplastic composition of claim 1 , wherein the poly(etherimide) comprises repeating units derived from bisphenol A dianhydride and m-phenylene diamine.

6 . The thermoplastic composition of claim 1 , wherein the poly(etherimide) is a poly(etherimide)-polysiloxane block copolymer, preferably comprising a poly(etherimide) block comprising repeating units derived from bisphenol A dianhydride and m-phenylene diamine and a poly(dimethyl siloxane) block.

7 . The thermoplastic composition of claim 1 , wherein the poly(etherimide) has one or more of:

a melt flow rate of 0.1 to 40 grams per 10 minutes, determined according to ASTM D1238 at 337° C. and under a load of 6.6 kg;

a weight average molecular weight of 10,000 to 150,000 grams per mole, determined by gel permeation chromatography using polystyrene standards; and

an intrinsic viscosity of greater than 0.2 deciliters per gram, determined in m-cresol at 25° C. by Ubbelohde viscometer.

8 . The thermoplastic composition of claim 1 , wherein the composition further comprises one or more of:

greater than 0 to 10 weight percent of a processing aid; and

greater than 0 to 10 weight percent of a thermoplastic polymer different from the poly(phenylene ether), the poly(amide), and the poly(etherimide);

wherein weight percent of each component is based on the total weight of the composition.

9 . The thermoplastic composition of claim 1 , wherein the reinforcing fiber comprises one or both of

an inorganic fiber comprising glass fiber, basalt fiber, or a combination thereof; and

an organic fiber comprising carbon fiber, aromatic poly(amide), or a combination thereof.

10 . The thermoplastic composition of claim 1 , wherein the reinforcing fiber comprises glass fiber, preferably wherein the glass fiber is E-glass fiber, S-glass fiber, R-glass fiber, or a combination thereof.

11 . The thermoplastic composition of claim 1 , wherein the composition further comprises an additive composition comprising a pigment, a processing aid, a flow promoter, a demolding agent, a thermal stabilizer, a light stabilizer, a UV absorbing additive, a compatibilizer, or a combination thereof.

12 . The thermoplastic composition of claim 1 , wherein the thermoplastic composition exhibits one or both of

improved tensile stress, tensile elongation, or both relative to the same thermoplastic composition excluding the poly(etherimide); and

improved hydrothermal aging performance relative to the same thermoplastic composition excluding the poly(etherimide).

13 . An article comprising the thermoplastic composition of claim 1 .

14 . The article of claim 13 , wherein the article is a molded article.

15 . A method of making the thermoplastic composition of claim 1 , the method comprising melt-mixing the components of the thermoplastic composition.
