Isoprene/2-vinyl pyridine block copolymer

The poly(styrene-b-isoprene) (P(S-b-IP)) and poly(-styrene-b-2-vinyl pyridine) (P(S-b-2VP)) block copolymers with narrow molecular weight distributions for blending with the microspheres were also synthesized using the additional anionic polymerization technique. The number-average molecular weights (Mns) and PS contents are also shown in Table 1. 

The Wiesner group applied the SNIPS process to poly(isoprene-h-styrene-h-4-vinyl pyridine) terpolymer to fabricate scalable membranes with high fluxes and sharp molecular weight cut-offs [47]. Introduction of the third, PI block generated membranes with improved mechanical properties over the diblock copolymer-based materials studied by Peinemann et al. Thus, besides BCP SA as a means to control stmcture, BCP architectures can further be employed to cmitrol the mechanical properties of nanomaterials.
