Interfacial behavior of block copolymers in situ-formed in reactive blending of dissimilar polymers

Solvent-free preparation, characterization, and properties of SEBS–g–polycarbonate copolymers

“…[32,33] A third attractive strategy, by a continuous process, consists to synthesize, in situ, a block or graft copolymer at the interface between the immiscible polymers. [24,[34][35][36][37][38][39][40][41][42][43][44][45][46] Reactive extrusion can then be used with the advantage to combine simultaneously both the blending and the chemical reaction with short residence times. These reactions often happen between two functional groups located at the end of the polymer chains.…”

Effect of a dual compatibilizer on the formation of co-continuous morphology of immiscible po`lymer blends

“…This implies that isolated PS particles are encapsulated by the PA6 domains. This is similar to "salami" structures formed through a phase inversion process (the PS minor phase melts first followed by the PA6 major phase during melt blending) [51] or the micellization of lSMA-g-PA6 graft copolymer chains during the melt blending process (graft copolymers are pulled off the interface by shear stress, forming micelles in the matrix) [52][53][54].…”

The Effect of Chain Architecture of In Situ Formed Copolymers on Interfacial Morphology of Reactive Polymer Blends

“…Inoue et al [14][15][16] showed that the chain architecture of in situ formed copolymer affected the final morphology of polyamide/polysulfone (PA6/PSU) blend. Micelle formation, in particular, under the shear for graft copolymers formed from phthalic anhydride mid-functionalized PSU was different from that for diblock copolymers formed from end-functionalized PSU.…”
