Glass transition temperature control by poly(norbornene-dicarboximide) copolymers

Studies on in situ magnetic alignment of bonded anisotropic Nd-Fe-B alloy powders

“…In addition, specific alignment configurations can be used to control the flux path in a magnetic circuit using anisotropic bonded magnets. Although the thermo-rheological properties of the polymer binders typically used in the manufacturing of bonded magnets may limit the maximum operating temperatures, it is worth noting that some polymers have operating temperatures higher than the maximum operating temperatures of many of the Nd-Fe-B magnet grades [10][11][12]. Enhancing the hard magnetic properties of bonded magnets via the use of anisotropic powders requires achieving a high degree of powder alignment within the binder.…”

Combining a ligand photogenerator and a Ru precatalyst: a photoinduced approach to cross-linked ROMP polymer films

“…As expected, the lowest T g value was found for pure pol-yNB (NB-100); the value of 27 C is fully consistent with literature data. 64,65 Upon increasing the content of DCPD, higher T g values were gradually obtained, with a maximum at 114 C found for DCPD-100. This tendency is likely to be caused by the increase of cross-linking density as more cyclopentene rings react.…”
