Anwendungen

2,3,4,5,6-Pentafluorostyrene is used in the synthesis of optically active copolymers having low surface energies by utilizing beta-pinene as another monomer. It is also used in the synthesis of fluorinated and photo crosslinkable liquid prepolymers, which is used for flexible optical waveguides. Polymeric fluorinated nano particles prepared using 2,3,4,5,6-Pentafluorostyrene and styrene is explored in magnetic resonance image (MRI) applications, since it has larger structural design potential compared to traditional systems like emulsions and solutions of smaller molecules.

Bemerkungen

Store in a cool and well ventilated area. Keep the container tightly closed, away from sources of ignition and direct sunlight. Incompatible with strong oxidizing agents, strong acids and bases.
