Co-existing morphologies of lamellae and double arrays of cylinders by A1BA2C tetrablock terpolymer

Giant, 2023
Here, we observed, via small-angle X-ray scattering and transmission electron microscopy, co-existing morphologies of lamellae and cylinders by precisely tailoring the volume fraction of each block in polystyrene-b-polyisoprene-b-polystyrene-b-poly(2 ...

Stabilization of colloidal palladium particles by a block copolymer of polystyrene and a block containing amide sidegroups [PDF]

, 1996
A block copolymer of polystyrene and poly(tert-butylmethacrylate) was prepared by anionic polymerization. The ester groups of the poly(tert-butylmethacrylate) were hydrolyzed, after wich the remaining carboxyl groups were reacted with pyrrolidine.
