Abstract

A resin blend is provided including a blend of resorcinol diphthalonitrile ether resin and a bisphenol M diphthalonitrile ether resin. Another resin blend is provided including a blend of resorcinol diphthalonitrile ether resin and a bisphenol T diphthalonitrile ether resin. The resin blends prior to cure have more favorable processing and curing properties compared to the resorcinol diphthalonitrile resin alone, enabling greater ease in manufacturing.

Claims

1. A resin blend comprising a blend of resorcinol diphthalonitrile ether resin and a bisphenol M diphthalonitrile ether resin, wherein the bisphenol M diphthalonitrile ether resin is of Formula I:

2. The resin blend of claim 1, wherein a weight ratio of the resorcinol diphthalonitrile ether resin to the bisphenol M diphthalonitrile ether resin ranges from 10:

90 to 90;

10, inclusive.

3. The resin blend of claim 1, further comprising at least one additive selected from a catalyst, a curative, a toughener, a filler, and combinations thereof.

4. The resin blend of claim 3, wherein the curative comprises an amine.

5. The resin blend of claim 3, wherein the curative comprises an aniline functional residue.

6. The resin blend of claim 5, wherein the curative comprises 4,4′

-(1,3-phenylenedioxy)dianiline.

7. The resin blend of claim 1, wherein the resin blend further comprises at least one additional phthalonitrile resin.

8. A resin blend comprising a blend of resorcinol diphthalonitrile ether resin and a bisphenol T diphthalonitrile ether resin, wherein the bisphenol T diphthalonitrile ether resin is of Formula II:

9. The resin blend of claim 8, wherein a weight ratio of the resorcinol diphthalonitrile ether resin to the bisphenol T diphthalonitrile ether resin ranges from 10:

90 to 90;

10, inclusive.

10. The resin blend of claim 8, further comprising at least one additive selected from a catalyst, a curative, a toughener, a filler, and combinations thereof.

11. The resin blend of claim 10, wherein the curative comprises an amine.

12. The resin blend of claim 10, wherein the curative comprises an aniline functional residue.

13. The resin blend of claim 10, wherein the curative comprises 4,4′

-(1,3-phenylenedioxy)dianiline.
