Abstract

Poly(ferrocenyldimethylsilane) (PFS) block copolymers form fiberlike micelles by a seeded growth process. This paper describes the effect of adding similar amounts of PFS block copolymers, PFS–PDMS and PFS–PI, to a common micelle seed. The lengths of the micelles obtained were strongly influenced by the degree of polymerization of the corona‐forming blocks. The change in length was due to a change in the number of polymer molecules per unit length of the micelle.

## Abstract Addition of a concentrated solution of PI~1000~–PFS~50~ dissolved in THF to a solution of PI~1000~–PFS~50~ seed micelles in decane led to the formation of uniform elongated fiberlike micelles with a narrow length distribution. When additional THF (>10 vol.‐%) was added to the micelles,
