A thermoset polymer product comprising 4,4'-(((3-oxo-isoindoline-1,1-diyl)bis(4,1-arylene))bis(oxy))dibenzonitrile units of formula (2)wherein the units are derived from a 4,4'-(((3-oxo-isoindoline-1,1-diyl)bis(4,1-arylene))bis(oxy))diphthalonitrile monomer of formula (1)wherein R is a Chydrocarbyl, preferably a Calkyl, a phenyl, or a phenyl substituted with up to five Calkyl groups, more preferably a Calkyl or a phenyl; each occurrence of Rand Ris independently a hydrogen, a halogen, or a Chydrocarbyl, preferably a hydrogen, a halogen, or a Calkyl, more preferably a hydrogen or a Calkyl; p and q are each independently 0 to 4, preferably 0 or 1, more preferably 0; and G is a residue of a cyano group, and is a Chydrocarbyl linking group having a valence of at least 2. |
