1. 1. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

   Kandidat-uppsats, KTH/Kemiteknik

   Författare :Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
   Nyckelord :Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

   Sammanfattning : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. LÄS MER

3. 2. Polymerization of Zwitterionic Sulphobetaine Methacrylate and Modification of Contact Lens Substrate

   Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

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

   Sammanfattning : 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. LÄS MER
