THERMAL BEHAVIORS OF INTRINSIC POLYANILINE AND ITS DERIVATIVES

Thermal properties of polyaniline (PAn), polytoluidine(POT) and polyanisidine(PAs) were examined by TG and DSC techniques. The weight-uptake of POT at 200-300 degrees C was observed and carefully discussed.

SOLUBLE POLY-(O,M)-TOLUIDINE

The soluble poly-o-toluidine (POT) and poly-m-toluidine (PMT) have been success- fully prepared under controlled conditions of polymerization and post-treatment, and characterized by IR, VPO and elemental analysis. It is found that the soluble and insol- uble polymers obtained with two different methods (Ⅰ and Ⅱ) have the similar conduc- tivity and molecular chain structure. VPO measurement shows that the number average molecular weight (Mn) of soluble polymers is about 3000. The mole ratio o...
