摘要:
AbstractSynthesis of both hydrocarbon and perfluorocarbon vinyl polymers containing the SF5group have been accomplished by the reaction of elemental fluorine with poly (S‐vinyl‐O‐t‐butylthiocar bonate(. The resulting linear polymers have pendant SF5groups with similar structures to polytetrafluoroethylene and polye

摘要:
AbstractCopolymers of 2‐hydroxyethylmethacrylate (HEMA) and glycidylmethacrylate (GMA) are useful for contact lenses. Copolymerization of HEMA and GMA was carried out in dimethylformamide medium using benzoylperoxide as initiator at 60°C. The composition of HEMA and GMA in copolymers was estimated using13C‐NMR. The reactivity ratio of HEMA and GMA was found to be r = 0.73 and r2= 0.98 by Finemann‐Ross method and r1= 0.74 and r2= 1.00 by Kelen‐Tudos methods. The experimental values are in close agreement with theoretical value determined from Q
