A FACILE SYNTHESIS OF HYPERBRANCHED POLYIMIDES FROM 2,6,12-TRIAMINOTRIPTYCENE

Received Date: 14 November 2008
Revised Date: 19 December 2008

Based on monomer 2,6,12-triaminotriptycene, hyperbranched polyimides with high molecular weight modified with different terminal functional groups were obtained by polymerization of A2 + B3 system. The prepared hyperbranched polyimides had good solubility in CHCl3, DMF and THF, and performed no detective Tgs in the range of 50-330°C and high Tds (5%) above 455°C.
