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 ...
A review in 4 sections comprising synthetic methods and prodn. processes of plastics (section I), apparatuses for prodn., processing, and making of plastics (section II), manufg. processes for the most important plastics (section III), and processing of th ...
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 ...
Reaction calorimetry is an efficient tool used to obtain kinetic, thermodn., and safety data. A new tool, composed of a high-pressure reactor (HP350) coupled with a Mettler-Toledo RC1e reaction calorimeter, is developed for the investigation of chem. react ...
Reaction calorimetry is an efficient tool used to obtain kinetic, thermodn. and safety data. A reaction calorimeter, RC1e-HP350, developed in collaboration with Mettler-Toledo GmbH, allows investigating chem. reactions under supercrit. conditions. The main ...
High-temp. polymn. has recently become of interest for industry because it yields higher reaction rates, and thus less reaction time, lower viscosity, and higher conversions. However, it also leads to new challenges for process engineering in regards to ma ...
Efficient stirring is needed to realize heat flow anal. with a thermally homogeneous medium. Because dispersion polymn. with supercrit. fluids can be destabilized under stirring, a preliminary target has been to find a compromise between synthesis and basi ...
Thermally unstable polymers such as poly(Me methacrylate) are degraded considerably during industrial processing. This degrdn. and its redn. to a min. were investigated in both lab and continuous pilot-scale expts. A three-step degrdn. mechanism, starting ...
Supercrit. fluids (SCFs) were intensively studied in the last decade as alternative, environment-friendly benign reaction solvents. A new anal. technique was derived from a combination of classical heat flow reaction calorimetry and the supercrit. fluid te ...
A review focuses on expts. describing the hydrodynamic behavior and the heat transfer properties of supercrit. CO2 and the application of supercrit. fluids in refrigeration and cooling. ...
