1. 6. Synthesis and assembly of biodegradable/ compatiblegraft copolymers for biomedical applications

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för kemi - Ångström

   Författare :Kristina Nilsson; [2011]
   Nyckelord :;

   Sammanfattning : The synthesis and characterization  of nanostructured block copolymers is described.Block copolymers were grafted onto a backbone polymer  that consists of themonomer  MTC-BuOBn.  The block copolymers have a part consisting of PTMC(trimethylene  carbonate) and a part consisting of PLLA.

3. 7. Designing star-like block-copolymers as compartmentalized nanostructures for drug delivery applications

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för materialkemi

   Författare :Johanna Engstrand; [2010]
   Nyckelord :drug delivery; polymer; ring opening polymerization; methyl trimethyl carbonates; block-copolymers; PEG;

   Sammanfattning : This thesis describes syntheses and characterization of star-like amphiphilic block copolymers consisting of poly(ethylene glycol) (PEG) as the hydrophilic block,polycarbonate as the hydrophobic block and an amine-containing dendrimer as the core molecule. The macromolecules were synthesized by either a convergent or adivergent approach that includes tandem click reactions and ring opening polymerizations (ROP) of methyl trimethyl carbonates (MTC) with differentfunctionalities.
