Formation of OBC, PPY and PBCs was ascertained through FT-IR spectra. SEM revels show porous morphology of PBCs. TG reveals multistep decomposition of OBC, whereas, PPY and [III] were decomposed in a single step. OBC, PPY and [III] has shown common TG onset at 200 oC with decreasing order of % Wr ranging 93.58 to 86.7. Moisture content of [III] (1.8%) was significantly controlled due to modification of PPY (4.75%) with OBC. The rate of expulsion of moisture by [III] (15.3 μg/min) was also controlled over PPY (7.5 μg/min). Maximum degradation of OBC was appeared @ 17.8 μg/min at 518 oC that was relatively low for PPY (@ 64μg/min). Modification of PPY with OBC has liberated [III] with maximum decomposition @ 47.6 μg/ min. This indicates the significance of OBC towards modification in thermal stability of PPYEnglishThesis
