In this study, the application of reaction calorimetry, an efficient tool to obtain kinetic and safety data, is presented on the free radical dispersion polymn. of MMA in scCO2. The effect of three major parameters with respect to the reaction evolution ar ...
This thesis is devoted to the study of the dispersion polymerization of methyl methacrylate in supercritical carbon dioxide (scCO2), using a poly(dimethylsiloxane) macromonomer (PDMS macromonomer) as stabilizer. Supercritical fluids (SCF) and SCF mixtures ...
Protein-polymer conjugates are widely used in biotechnology and medicine, and non-toxic polymers for bioconjugation would be advantageous for these applications. Herein, we reported the toxicity of polymers synthesized by two commonly employed controlled r ...
As the need for lower mol. wt. acrylates for specialty and molding applications increases, industry is looking for substitute prodn. processes. An alternative to the increasing of initiator and chain transfer agent concn. is working at higher temps. Howeve ...
The present PhD thesis deals with the high temperature polymerization of methyl methacrylate in a continuous pilot scale process. The major aim is to investigate the feasibility of a polymerization process for the production of PMMA molding compound at tem ...
Proteins have been modified with polymers in diverse manners over the past 30 years. However, while proteins have been used to prepare many functional constructs, they are sensitive biomolecules and their bioactivity can be either positively or negatively ...
Free radical polymerization is the most frequently used technique to produce synthetic polymers. They represent more than 25% of the total volume of materials made by the mankind. 3% thereof correspond to water soluble polymers with annual growth rates est ...
The polymer APFO3 was prepd. with different mol. wts. to study how the infiltration into nanoporous TiO2 films of different thickness depends on the size of the polymer. Also two different sizes of TiO2 nanoparticles were investigated to understand the eff ...
We investigate in this work the fabrication of polymer fluidic and mechanical devices based on evaporable compounds as sacrificial layers using the screen-printing process. The combination of thermosetting polymer resins with evaporable compounds as sacrif ...
This contribution reports on the synthesis of hyperbranched polylysines via thermal polymerization of L-lysine hydrochloride. Polymerization of L-lysine hydrochloride in the presence of one equivalent KOH at 150°C resulted in polymers with a number-average ...
