Why Block Copolymers??

Lateral Phase<Separation of PMMA-blockPOMA on Mica.

Phase Diagram of Pluronics P84 (E19P44E19).

AB Diblockcopolymers

Triblockcopolymers

ABC=(A)x(B)y(C)z

ABA=(A)x(B)Y(A)z

ABC=(A)x(B)y(C)z

amphi = of both kinds philic = having affinity for

- at least two chemically different parts in one polymer based on different monomers

show phase-separation in the solid-state, in selective solvents, on surfaces.

Blockcopolymer:

Makromolecule, that is composed of at least two different monomers in a block-like structure. (AB, ABA, ABC...)

Amphiphilic Structures

low molecular weight amphiphile polymeric amphiphiles
