Block and Graft Copolymers Containing Poly(dimethylsiloxane) and Poly(4-vinyl-pyridine) Segments by Free Radical Polymerization

摘要

Polysiloxanes with terminal or pendent aldehyde functionality can be used as components of copper salt-based redox initiation systems to prepare block, graft and crosslinked copolymers containing poly(4-vinylpyridine) and polysiloxane segments. The block and graft copolymers form very viscous solutions in dilute HCl and have useful anti-foam activity.
