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 ...
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 ...
L-lysine is an essential a-amino acid and a necessary building block for all proteins in the body. As an essential amino acid, L-lysine is not synthesized by humans or animals. Industrially produced L-lysine has therefore a big market as food additive, e.g ...
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 ...
Inkjet printing (IJP) is a contactless method of printing and has found wide applications in the packaging and printing industries. In order to get patterned micro-structures with specific morphology via inkjet technology, predefined molds from SU8 with di ...
A precise data set describing the kinetics of the free radical copolymn. of acrylamide/acrylic acid (AM/AA) in the range of low total monomer concn. as a function of the pH, total monomer concn., initiator concn., and comonomer ratio is presented. Strong i ...
A new class of water-soluble, amphiphilic star block copolymers with a large number of arms was prepared by sequential atom transfer radical polymerization (ATRP) of n-butyl methacrylate (BMA) and poly-(ethylene glycol) methyl ether methacrylate (PEGMA). A ...
Several researches have dealt with the thermal initiation of Me methacrylate (MMA) in the past. Some of them already discussed the presence of peroxide contg. species that are formed from dissolved oxygen and the monomer itself as main reason for this init ...
An anal. approach to predict copolymer compns. is presented for the particular case that the reactivity of one monomer (B) alters under the influence of one measurable medium parameter. Terpolymn. math. treatment was applied to binary systems (A/B), which ...
The kinetic properties of the Me methacrylate (MMA) polymn. at pilot scale for a given temp. range (130-170 Deg) were detd. by differential scanning calorimetry and batch expts. reflecting initiation by MMA peroxides, depropagation of the living chains as ...
