Abstract:A novel alicyclic dianhydride monomer,1,2;3,4-cyclobutane-bis(3,6-oxa-1,2,3,6-tetrahydrabenzene-1,2-dimethyl acid anhydride)(CBTDA) was synthesized through Diels-Alder and cyclization reaction and characterized.A series of alicyclic polyimides were successfully synthesized from it and common aromatic diamines,4,4'-Diamino-3,3'-dimethyl diphenylmethane(DADMDPM) and 4,4'-Diaminodiphenyl ether(DADPE) by condensation followed by chemical imidizaition and thermal imidization.The alicyclic polyimides obtained exhibite many useful physical properties,such as good solubility in strong polar solvents,high glasstransition temperatures and high thermal decomposition temperatures,excellent transparency,and good dielectric properties.
Keywords:alicyclic polyimides  alicyclic dianhydride  1  2  3  4-cyclobutane-bis-(3  6-oxa-1  2  3  6-tetrahydrabenzene-1  2-dimethyl acid anhydride)(CBTDA)
