The effect of crosslinking on thermal and mechanical properties of perfluorocyclobutane aromatic ether polymers

Heat-induced crack healing in a perfluorocyclobutane-containing polymer

“…This is in accord with the previously reported result. 19 The polymerization produced a very hard film that was insoluble in organic solvents.…”

Utilization of a Meldrum's acid towards functionalized fluoropolymers possessing dual reactivity for thermal crosslinking and post-polymerization modification

“…The newly designed Meldrum's acid functionalized aryl TFVE monomer 5 was synthesized in a good isolated yield (80%) by simple alkylation of Meldrum's acid with 4-trifluorovinyl benzyl bromide 4 by following standard procedure in Scheme 2. 20 A single crystal X-ray diffraction study was carried out on monomer 5 and the molecular structure is also shown Scheme 2 inset. Experimental parameters as well as packing views are provided in the ESI.…”

Structure-property relationship of fluorinated co-poly(arylene ether sulfide)s and co-poly(arylene ether sulfone)s for low-loss and low-birefringence waveguide devices

“…The densities are reasonable if we consider that the polymers are fluorinated and contain a sulfone or sulfide group. In the table, the calculated density of common polymers such as polymethylmethacrylate, polystyrene, polyamides, polycarbonate, perfluorocyclobutane (PFCB), Cytop, and polyimide (6FDA-TFDB) are included and compared with the experimentally obtained density [7], [23], [24]. The calculate densities match very well with the experimental data.…”
