Synthesis, spectral and thermal characterization of polyester derived from 1,1-bis(4-hydroxyphenyl)cyclohexane

Abstract

A series of polyesters with pendant cyclohexane ring as a cardo group were synthesized by reacting 1,1-bis(4-hydroxyphenyl)cylcohexane (bisphenol-Z (BPZ)) with diacid chlorides. The molecular structures of the monomer and polymers were confirmed by spectral analyses. Thermal properties were studied using thermogravimetric analysis and differential scanning calorimetry. The thermogravimetric data revealed that the polymers are stable up to 190 C and start to degrade thereafter. The thermal stability initially increases with increase in spacer length and then decreases due to negative effects of the spacer. In the present study, Arrhenius, Broido and Horowitz-Metzger models have been used to calculate the degradation kinetic parameters.

Synthesis, Characterization, and Application of Poly(4,4'-Cyclohexylidene Bisphenol Oxalate) for Solid-Phase Extraction of DNA

“…The free oxalyl chloride appeared slightly downfield at 159 ppm but the peak of carbonyl carbon of oxalyl group attachment of bisphenol Z led to an upfield shift at 154 ppm. This analysis is conformed with the data reported in the literature studies [26, 27]. Furthermore, the advantage of 13 C NMR spectrum of poly(4,4'-cyclohexylidene bisphenol oxalate) is also worth mentioning.…”

High-solubility aromatic polyesters with fluorene and phthalein groups: Synthesis and property

“…13,14 Various cardo groups have been introduced into aromatic polyesters. [15][16][17][18] Such groups were introduced into the macromolecule via bisphenols of appropriate structures and diacid chlorides. Among the wide diversity of cardo monomers, phenolphthalein (PP) 19,20 and 9,9-bis(4-hydroxyphenyl)fluorene (BPF) 10,21,22 have attracted much attention because of their unique characteristics that originate from their structure.…”

Preparation and characterization of novel soluble polyarylates derived from 9,9-bis[4-(4-chloroformylphenoxy)phenyl]xanthene with various bisphenols

“…Some cardo groups such as fluorene, phthalide, phthalimidine, decahydronaphthalene, cyclohexyl, and tricyclo[5.2.1.0]decyl in the repeat unit of the polyesters have been explored. 14 –20 In this article, we wish to report the synthesis and characterization of a series of new aromatic polyesters containing cardo xanthene group by phase-transfer-catalyzed interfacial polycondensation of 9,9-bis[4-(4-chloroformylphenoxy)phenyl]xanthene (BCPX) 21 with various bisphenols such as 2,2-bis(4-hydroxyphenyl)propane and 4,4′-(hexafluoroisopropylidene)diphenol. The resulting polyarylates were characterized by Fourier transform infrared (FTIR), Proton nuclear magnetic resonance ( 1 H NMR) spectroscopy, and elemental analyses, and their general properties such as crystallinity, solubility, and thermal properties were investigated.…”
