## Abstract Two series of poly(ether imide)s (PEIs) containing fluorenyl cardo groups in the main chains were synthesized, which are derived from the polycondensation of 9,9โฒโbis(4โaminophenoxyphenyl)fluorene (BAOFL) or 9,9โฒโbis(3โtrifluoromethyl,4โaminophenoxyphenyl)fluorene (6FโBAOFL) with four k
Diphenylacetylenes having a dimethyloctylsilyl group and an alkyl group at para positions [Me 2 n-C 8 H 17 SiC 6 H 4 C^CC 6 H 4 R; R ยผ H (1a), i-Pr (1b), t-Bu (1c), n-Bu (1d)] and having only an alkyl group [PhC^CC 6 H 4 R; R ยผ i-Pr (1B), t-Bu (1C)] were synthesized and then polymerized with TaCl 5
Diarylacetylene monomers having trimethylsilyl groups and other substituents (substituted biphenyl, 1a and 1b; trimethylsilylmethylphenyl, 1cee) were synthesized and polymerized with TaCl 5 -n-Bu 4 Sn catalyst to produce the corresponding poly(diarylacetylene)s (2aed). Polymers 2aec had high molecul
