Abstract :
[en] Diblock copolymers of polystyrene and polydimethylsiloxane, and polystyrene end‐capped with a fluorinated group have been prepared by anionic polymerization. Polymethylmethacrylate end‐capped with the same fluorinated group has been synthesized by a telomerization technique. Surface activity of all these compounds has been studied in solution by tensiometry and in a polymeric matrix by various methods: XPS and measurements of wettability and contact angle. The relative interactions of the dispersion medium with each component of the additive are of a prime importance in the control of the surface energy. Copyright © 1990 Wiley‐VCH Verlag GmbH & Co.
