Patent ID: 8691932

Claim:
A thermosetting monomer comprising at least two of an aryl-cyanato group and at least two of a phosphorus group, where the thermosetting monomer is represented by a compound of Formula (I): wherein m is an integer from 1 to 20; wherein n is an integer from 0 to 20 with the proviso that when n is 0 then m is an integer from 2 to 20; wherein X is selected from the group consisting of sulfur, oxygen, and a lone electron pair; wherein each R 1 and R 2 is independently a hydrogen, an aliphatic moiety having 1 to 20 carbon atoms, or aromatic hydrocarbon moiety having 6 to 20 carbon atoms, where the aliphatic moiety and the aromatic hydrocarbon moiety can be joined to form a cyclic structure; wherein R 3 is selected from the group consisting of a hydrogen, an aliphatic moiety having 1 to 20 carbon atoms, an aromatic hydrocarbon moiety having 6 to 20 carbon atoms, R 4 R 5 P(═X)CH 2 —, and ROCH 2 —, where R is an aliphatic moiety having 1 to 20 carbon atoms; and wherein each R 4 and R 5 is inde endentl an aliphatic moiety havin 1 to 20 carbon atoms, an aromatic hydrocarbon moiety having 6 to 20 carbon atoms, where the aliphatic moiety and the aromatic hydrocarbon moiety can be joined to form a cyclic structure, RX—, or wherein R 4 and R 5 together are Ar 2 X—; and wherein each Ar 1 and Ar 2 is independently a benzene, a naphthalene, or a biphenyl.
