Abstract
Chapter 1 is a general introduction of the whole thesis and it features the main concepts of this
project.
Chapter 2 reports the synthesis and self- assembly of a temperature-responsive DMAP
containing nanoreactor. The DMAP motif is incorporated in to a monomer and polymerized
by RAFT with styrene in order to form the hydrophobic block of a polymeric micelle. The shell
of the micelle is formed by chain extension of the styrenic block with NIPAM, which provides
temperature responsive properties to the system.
In Chapter 3, the concept of using polymeric micelles to catalyze organic reactions in water is
presented and compared to surfactant based micelles in the context of molecular recognition,
achieving enzyme-like specific catalysis by tethering the catalyst in the well-defined
hydrophobic core of a polymeric micelle
In Chapter 4, the incorporation of different catalytic amino motifs into a polymer backbone is
investigated by RAFT polymerization in order to catalyze the reaction between polyalcohols
and polyisocyanates in the formation of polyurethane foams.
In the final chapter, the stimuli-responsive properties of DMAEA containing polymers are
investigated. DMAEA is copolymerized by RAFT with the non-responsive MA at different
loadings in order to study how the distance between amine motifs affects the polymer LCST
and pKas .values
