Verwenden
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.
Verwenden
Copolymers of 2,3,4,5,6-Pentafluorostyrene and N-phenylmaleimide were synthesized by free radical polymerization. Diblock copolymers of D,L-lactide and pentafluorostyrene with narrow molecular weight distributions have been reported. Fluorinated and photocrosslinkable liquid prepolymers have been synthesized for flexible optical waveguides, the prepolymers are photocurable to afford flexible and transparent films. Phase copolymers consisting of poly(methylmethacrylate) (p-MMA)/n-butylacrylate (nBA) and poly(nBA)/pentafluorostyrene (p-PFS)have been prepared.
Allgemeine Beschreibung
2,3,4,5,6-Pentafluorostyrene is a fluorinated monomer.
