dc.description.abstract | Aromatic diamine monomers, including m-phenylenediamine (mPD), 2-methyl-m-phenylenediamine
(2Me-mPD), 4-methyl-m-phenylenediamine (4Me-mPD) and trimethyl-mphenylenediamine
(tMe-mPD), were polymerized by chemical oxidation using ammonium
persulfate as an oxidant. Aluminium triflate (Al(OTf)3) was also used for the first time as a
co-catalyst under various polymerization conditions. The polymerization yield was
improved when Al(OTf)3 was introduced to the polymerization reaction for most polymers.
The poly(2-methyl-m-phenylenediamine) (P(2Me-mPD)), poly(4-methyl-m-phenylenediamine)
(P(4Me-mPD)) and poly(trimethyl-m-phenylenediamine) (P(tMe-mPD)) polymers
exhibited better solubility than poly(m-phenylenediamine) (P(mPD)) polymers in most
common solvents. The homopolymers obtained were characterized by FT-IR, 1H and 13C
NMR, WAXD and TGA. The results showed that the yield, solubility and structure of the
polymers are significantly dependent on the polymerization conditions. TGA measurements
indicated that the polymers have good thermal stability and decompose above
400 C in nitrogen. | en_US |
