1. Polycyanates of the formula: where each m independently has a value of zero to 3; p has a value of one to 20; each R is independently halogen; nitrile; nitro; C1-C6 alkyl or C1-C6 alkoxy; wherein the alkyl and alkoxy groups may be substituted with one or more halogen atoms, C2-C6 alkenyl, or C2-C6 alkenyloxy; each Z is H or —C≡N, wherein at least 25% of the Z groups are —C≡N; and each Q is independently hydrogen or C1-C6 alkyl, or when m is 2, two R groups may independently be a C3-C4 alkylene group that optionally contains one or two double bonds and is bonded to two adjacent carbons on the ring to which they are attached; thereby producing a fused, bicyclic ring.
