Strained Metallocenophanes: Potential Monomers for Metallopolymers
… and Sp,Sp-108Tip were unsuccessful and both monomers polymerized at 100-130 °C. A series of [2]ferrocenophanes bridged by carbon and either silicon (CSi-145), phosphorous (CP-146), and boron (CB-112) were synthesized and characterized. The molecular structures of all three [2]ferrocenophanes …

Living cationic polymerization of styrene monomers
This thesis describes an experimental investigation of synthesis of polystyrene under various polymerization conditions such as solvent polarity, temperature, initial concentrations of initiator, catalyst, monomer and added salts or co-catalyst, which was achieved using the living cationic …

Synthesis and controlled radical polymerization of multifunctional monomers
Multifunctional monomers on the basis of acryl- and methacryl derivatives were synthesized and different protective groups were used. After polymerization the protective groups were removed by different methods. Various initiators for the NMP of the monomers were synthesized and the reaction …

Synthesis of novel cylic monomers for hydrogel polymers
… is reported. Hydrogels containing these monomers showed significant improvements in both tensile strength and Youngs modulus, at both equivalent composition and water content, over the corresponding HEMA / styrene and HEMA / methyl methacrylate analogues. It was observed that derivatives …

Interactions of Phenolic Monomers With Digestion and Metabolism
… Roughages differed in content of phenolic monomers, with grasses generally having higher concentrations. In vitro incubation of alfalfa hay, smooth bromegrass hay and ensiled cornstalks with rumen fluid resulted in apparent digestion of phenolics associated with cell wall material. …

Macrocyclic Monomers: Synthesis, Characterization and Ring-opening Polymerization
Interest in macrocyclic monomers can be dated back to the 1960's. The recent surge of research activities in this area is prompted by two facts: the encouraging discovery of high yield synthesis and facile ring-opening polymerization of cyclic polycarbonate; the need for a technique to solve the …

Design, Synthesis, and Characterization of Triazaadamantane Based Monomers and Dendrimers
These triazaadamantane macromolecules may find broad application as drug carriers and for the encapsulation and release of other substances, similar to the Trojan horse strategy. Their ability to act as proton sponges makes them particularly interesting with regards to their potential as artificial …

Production of Bio-based Lactone Monomers for Intrinsically Recyclable Plastics
… the development of scalable synthesis of the monomers for these plastics lags behind. This work aims to develop methods for the synthesis of monomers using heterogeneous catalysts to allow for scaling-up. First, we used a high-throughput computational method to screen binding energies of key …

Hydrogen bonded cavity and polymeric nanotubular assemblies from small bicyclic monomers /
… that allow control of supramolecular outcome of monomers containing bicyclic framework fused with isocytosine and/or ureidopyrimidinone motifs are discussed. The control over aggregation is attained by changing the size of the side chains and by attaching carbamide substituents at the isocytosine …

Synthesis and Characterisation of N-substituted Pyrrole Monomers and Polypyrrole Films
… the polymerisation of N-substituted pyrrole monomers and the functionalisation of the monomers or the resulting polymers, with transition metal complexes, were performed. Polymer deposition was executed, utilising the electrochemical deposition technique, due to its facile use and the …

Polymerizable Peptide Monomers for the Targeted and Intracellular Delivery of Cancer Therapeutics
For the treatment of cancer, peptides hold great potential as both targeting and therapeutic agents. One particularly promising anti-cancer strategy is peptides derived from the third Bcl-2 homology domain (BH3), which antagonize pro-survival Bcl-2 proteins and induce apoptosis. Unfortunately, …
