Properties and Synthesis of Polyimides Based on 4-Octyloxy-Biphenyl-3,5-Diaminobenzoate
摘要
Abstract
The first series of polyimides with different ratio of side chain were copolymerized from 4-octyloxy-biphenyl-3,5-diaminobenzoate(C8) ,3,3' -dimethyl -4,4' -methyl-enedianiline (DMMDA) and 4,4-oxydiphthalic(ODPA) via one-step method.The effect of the diamine content of these PIs on their solubility,alignment,pretilt angle and thermal stability was investigated.Similarly, the second series of polyimides with different main chain were copolymerized from C8, DMMDA and different dianhydrides which include ODPA, pyromellitic dianhydride (PMDA), 3, 3', 4, 4'-dibenzophenonetetracarboxylic dianhydride (BTDA) via one-step method.The effect of dianhydride structure on the solubility and thermal stability was explored.关键词
