Poly (4, 4'-Cyclopentylidene diphenylene toluene – 2,4-disulfonate) (PSBPCT) has been Synthesized by Conventional interfacial poly condensation of 1, 1'-bis (4-hydroxyphenyl) cyclopentane (0.005 mol) and toluene-2, 4-disulfonyl chloride (0.005 mol) using water (50 ml) – chloroform (10ml) as inter phase, alkali (0.015 mol) as acid acceptor and cetyltrimethyl ammonium bromide (0.125g) as emulsifier. The structure of compounds has been supported by Infra-red and nuclear magnetic resonance spectral data. Thermogravimetric (t.g.a.) measurement has been made at four different heating rates and 100C min-1, respectively in N2 atmosphere. PSBPCT is stable up to about 3550C in N2 atmosphere and involves two-step degradation.
