  4. 23. Polymerization of Zwitterionic Sulphobetaine Methacrylate and Modification of Contact Lens Substrate

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Tobias Ingverud; [2015]
    Keywords : Zwitterionic; Sulphobetaine; RAFT; ATRP; End-group-modification; Grafting-to; Contact lens; zwitterjonisk; RAFT; ATRP; ändgrupps modifiering; ympning-till; kontakt;

    Abstract : In this study, the zwitterionic monomer [2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) was polymerized in a controlled manner by reversible addition-fragmentation chain transfer (RAFT) polymerization. The SBMA was also polymerized by atom transfer radical polymerization (ATRP) but in a less controlled manner why ATRP was discarded for further use in the study. READ MORE

  5. 24. Kan hundar nosa sig till cancer i blodprov? : en studie av tränade sökhundars förmåga att detektera tumörsjukdom i serum
