Thesis (MSc)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: The combination of natural and synthetic polymers allow for the synthesis of advanced hybrid copolymers. These hybrid copolymers have applications in biomedical areas, one such area being in drug delivery systems (DDS). In this study, a modular approach was used to prepare amphiphilic block copolymers with the ability to self-assemble into three dimensional structures. Reversible addition-fragmentation chain transfer (RAFT) was the synthetic tool used to mediate the polymerization of N-vinylpyrrolidone. RAFT is a versatile

Block copolymers of poly(lactide) and poly(carbonate) were synthetized in three different compositions and characterized by 1H-NMR and ATR analyses.

SEM micrographs show that all the blends exhibit the typical sea-island morphology characteristic of immiscible blends with PCL finely dispersed in droplets on a PLA matrix. Upon the addiction of the copolymers a reduction on PCL droplets size is observable. At the same time, a Tg depression of the PLA phase is detected when the copolymers are added in the

Abstract:

The miscibility of poly(vinyl pyrrolidone) PVP with copolymers of vinyl butyral and vinyl alcohol, containing 11% and 19% by weight of vinyl alcohol, has been investigated. To examine how the state of miscibility of these blends varies with the vinyl alcohol content of the copolymers, differential scanning calorimetry(DSC) and solid-state NMR methods were employed. PVP was found to form miscible blends with poly(vinyl butyral) PVB, containing 11wt% of vinyl alcohol, up to a weight ratio of 40/60(PVP/PVB11). At higher PVP loading, phase separated blends were obtained. In contrast, poly(vinyl bu

Abstract:

Poly(vinyl chloride) (PVC) requires the addition of large quantities of plasticizers in order to improve the flexibility and processability of the polymer. Since the plasticizer is not bound to the PVC polymer matrix, there is a tendency of the plasticizer to migrate into the surroundings. The most commonly used PVC plasticizer, di-2-ethylhexyl phthalate (DEHP), has become a ubiquitous environmental contaminant. As with other plasticizers, it may either accumulate or lead to the formation of metabolites, which resist further degradation and can themselves be toxic. Accordingly, there is incent

Firstly, naphthalenediols, substituted hydroquinones, or isosorbide was condensed with 4-nitrobenzoyl chloride. Secondly, the obtained l,4-bis(nitrobenzoyloxy) derivatives were reduced to the corresponding diarnines by Pd/C catalytic hydrogenation. A series of novel poly(arnide-ester)s were synthesized by direct polycondensation. The structures and thermal properties of synthesized polymers were examined by FT

Abstract:

碩士<br>國立交通大學<br>統計學研究所<br>101<br>Polya tree process is a large class of prior distributions, which Dirichlet process is included as a special case of Polya trees process. Like Dirichlet prior, the Polya tree prior also able to form a conjugate class for the posterior distributions. However, Polya tree process is different from Dirichlet process in two aspects: First, the Polya tree process is determined by a large collection of parameters and thus provide means to incorporate a wide range of beliefs. Second, some Polya trees assign probability 1 to the set of continuous distributions by (Kraft

Abstract:

Humane gamma delta T-Zellen stellen eine Gruppe von T-Lymphozyten dar, die neben NKT- und NK-Zellen auch als lymphatische Effektorzellen der angeborenen Immunität beschrieben werden. Nach ihrer Stimulierung tragen sie, in Analogie zu den NK-Zellen, zur schnellen, unspezifischen Infektionsabwehr bei. In dieser Arbeit wurde erstmals der Einfluss von ds-RNS (Poly (I:C)) auf humane gamma delta T-Zellen untersucht. Diese Substanz simuliert in vivo und in vitro die Infektion mit einem Virus und übt pleiotrope Effekte auf eine Reihe von verschiedenen Zellen aus, u. a. auch auf NK-Zellen. Diese Arbeit
