Pyrolysis of poly(phenylene vinylene)s with polycaprolactone side chains

Smart design for a flexible, functionalized and electroresponsive hybrid platform based on poly(3,4-ethylenedioxythiophene) derivatives to improve cell viability

“…56 Moreover, in previous studies related to other electroactive PCL-containing macromonomers, was experimentally found that PCL thermal stability depends on and it is increased by the aromatic moiety attached to it. 57,58 This trend is also confirmed in the present case of EDOT-PCL, for which polymerization degree of PCL is 16.5 as determined from 1 H-NMR results. The EDOT moiety placed at one of the PCL chain ends increased its thermal stability by increasing the IDT with 20 ºC (from the reported value of 230 ºC 56 to 250 ºC).…”

Original Macromolecular Architectures Based on poly(ε-caprolactone) and poly(ε-thiocaprolactone) Grafted onto Chitosan Backbone

“…Thermal degradation of PCL occurred in two stages. First chain scissions (around 220 °C) took place then depolymerization reactions occurred between 250 and 320 °C [15,25,26,27]. PCL thus showed two distinct peaks in DTG plot at 212 and 294 °C, which was consistent with the results that are reported in the literature.…”

Mass Spectrometry of Synthetic Polymers

“…This proposed procedure improves conventional direct Py-GC/MS and led to unambiguous identification of polyvinyl resins, in particular, poly(vinyl acetate) emulsions widely used in contemporary paintings , . Direct insertion probe pyrolysis MS was applied for monitoring the thermal degradation of electrochemically prepared polyaniline, polypyrrole, their composites/copolymers, and a BF 4 -doped conducting pyrrole copolymer , , as well as for studying the thermal degradation characteristics of PS and poly(ε-caprolactone) macromonomers , . A new application of synchrotron vacuum ultraviolet photoionization MS in the study of the thermal decomposition of poly(vinylchloride) (PVC) and PS were reported by Li et al .…”
