High Yields

A series of well-defined diblock copolymers containing PMMA, PEMA and PBMA blocks were synthesized with narrow MWDs and high yields via anionic polymerization, while t-BuOK was selected as initiator in THF at 0 °C. .

Living Polymerizations

Abstract A variety of living polymerization systems are now available for the controlled synthesis of block copolymers. Although living anionic polymerization remains as the method of choice for the most precise structural control, living polymerizations proceeding via other mechanistic types provide extremely useful extensions of this methodology to a wider variety of monomers.

Molecular Weights

Living anionic polymerization of 4-diphenylphosphino styrene (DPPS) achieved well-defined homopolymers, poly(DPPS-b-S) styrenic block copolymers, and poly(I-b-DPPS) diene-based diblock copolymers with predictable molecular weights and narrow polydispersities.
