Blends of alicyclic imide moiety and phthalontrile show highly efficient Thermal Synergistic Polymerization effect.
C
N of the phthalonitrile could be completely and rapidly consumed, with no triazine, minor phthalocyanine and primary polyisoindolines formation.
The reaction between alicyclic imide moiety and phthalonitrile suggests a free radical process.
The cured polymers showed excellent thermal properties, low boiling water absorbance and moderate dielectric constant.
