Investigation of Copolymers of Thiophene‐Functionalized Polystyrene with Pyrrole by Pyrolysis Mass Spectrometry

Pyrolysis of polyphenylenes with PCL or/and PSt side chains

“…For both polymers 5 and 6, the pyrolysis mass spectra were dominated with diagnostic peaks of styrene. Thermal degradation of polystyrene, PSt, has been the topic of several studies [31,32]. It is known that the PSt degrades in a single stage by a depolymerization reaction yielding mainly the monomer, styrene and some low molecular weight oligomers.…”

Mass Spectrometry of Synthetic Polymers

“…Direct py-MS of electrochemically synthesized thiophenefunctionalized polystyrene and pyrrole (PS/PPy) and their copolymers revealed the growth of polypyrrole onto the pendant thiophene moiety of polystyrene (152). The same technique was also used to study the thermal behavior of copolymers of thiophene with decanedioic acid bis-(2-thiophen-3-yl-ethyl)ester (DATE) and terephthalic acid his(2-thiophen-3-yl-ethyl)ester (TATE) prepared by potentiostatic polymerization.…”

Reversible addition–fragmentation chain transfer polymerization of styrene using a novel thiophene dithioester as the reversible addition–fragmentation chain transfer agent

“…A number of techniques for the preparation of polymers with desired end groups have been developed, such as the functional initiator approach, 33 ATRP, 34 and NMP. 35 In this study, two novel thiophene dithioesters were synthesized and used as RAFT agents to carry out styrene RAFT polymerizations. Polymers endlabeled with thiophene were successfully prepared, and this provides a powerful tool for the synthesis of vinyl and thiophene block copolymers to improve the properties of polythiophene.…”
