Abstract:
A resin blend is provided including a blend of a benzoxazine resin and a phthalonitrile resin. The benzoxazine/phthalonitrile resin blends prior to cure have more favorable processing and curing properties compared to the phthalonitrile resins alone, enabling greater ease in manufacturing.

Claim (Index 6):
The resin blend of  claim 1 , wherein the phthalonitrile resin is of Formula IV: where R is selected from H, a covalent bond, \u2014C(CH 3 ) 3 , a C4-C20 alkyl chain, \u2014NO 2 , \u2014NH 2 , a phenol, biphenol, bisphenol, a polyvalent phenol, an imide, an ether, a thioether, amide, ester, a polyvalent (hetero)hydrocarbyl residue; and y is at least 1; with the proviso that R is not of Formula V or Formula VI: wherein each R 1  is H or an alkyl group, and is the residue of an aliphatic aldehyde, R 2  is a covalent bond, or a polyvalent (hetero)hydrocarbyl group, preferably a covalent bond or a divalent alkyl group; R 3  and R 4  are independently selected from the (hetero)hydrocarbyl residues of a primary amino compound; and wherein each R 1  is H or an alkyl group, and is the residue of an aliphatic aldehyde, R 2  is H, a covalent bond, a phenol or a polyvalent (hetero)hydrocarbyl group, preferably H, a covalent bond or a divalent alkyl group; R 4  is a (hetero)hydrocarbyl residue of a primary amino compound, R 4 (NH 2 ) m , where when R 4  is an aryl group, m is 1-4; and x is at least 1.
