A resin composition for use in making pre-pregs and structural laminates contains a functionalized poly(phenylene ether) having the structure below: a radical initiator, the radical initiator being from about 0.1% to about 0.5% by weight of the composition; an unsaturated monomer; and a flame retardant comprising the compound 1,1'(ethane-1,2-diyl)bis[pentabromobenzene]. In the above structure, Y, m and n are defined in the Specification.

Thermosetting resin composition containing a polyphenylene ether and a brominated fire retardant compound

A resin composition for use in making pre-pregs and structural laminates contains a curable composition comprising: 

Resin systems containing a dicyclopentadiene-based epoxy resin and an ortho-alkylated aromatic diamine hardener exhibit low moisture absorption, high Tg and good retention of properties under hot and wet conditions. These properties make the resin systems especially useful in aerospace applications.

Low moisture absorption epoxy resin systems with alkylated diamine hardeners

A polymer composition especially suitable for producing fiber-reinforced structures having advantageous fracture toughness comprises a polyarylsulphone component and a thermoset resin component, each of which components is present at least partly as a phase continuous in at least one dimension. Preferred polyarylsulphones contain repeating units (PhSO.sub.2 Ph).sub.n and (Ph).sub.a linked through ether and/or thioether, where Ph is phenylene, n=1 to 2 and a=1 to 3; and such polyarylsulphones having amino end groups are provided as new compounds. The compositions can be made by spinodal decomposition of a mixture of the polyarylsulphone and a thermoset resin precursor.
