Synthesis of Polymeric Nanoparticles by Reversible Addition-fragmentation Chain Transfer (raft) Polymerization in Co2-induced Miniemulsion
Implementation of controlled/living radical polymerization in miniemulsion (typically with oil droplet diameter of 20-500 nm) for synthesis of well-defined, polymeric nanoparticles is of particular interest as miniemulsions possess the inherent advantage that ideally each monomer droplet is transformed into a polymer particles(Zetterlund et al., 2008). However, the high energy requirement for m...
متن کاملUltrasonic in-line monitoring of styrene miniemulsion polymerization
Ultrasonic transmission is a simple, non-destructive method to characterize turbid systems like e.g. emulsions or polymer dispersion. Here we use this technique for in-line monitoring of the miniemulsion polymerization of styrene. Either the ultrasound attenuation or the velocity signal provides a fingerprint characterizing the reaction process. During the reaction process the sound velocity in...
متن کاملMiniemulsion polymerization of styrene in the presence of macromonomeric initiators
Macromonomeric azo initiators (macroinimers, MIM) which have the properties of macromonomers, macrocrosslinkers and macroinitiators in a macrostructure were used in miniemulsion polymerization of styrene in the presence or absence of any other stabilizer and initiator. MIMs were prepared from the reaction of 4,40-dicyano-4,40-azovaleryl chloride, with poly(ethylene glycol) (PEG) of different mo...
متن کاملNANOENCAPSULATION OF n-OCTADECANE USING RAFT MINIEMULSION POLYMERIZATION
Miniemulsion polymerization technique has been used extensively for preparing small sized uniform particles of polymers, core-shell polymer particles, hybrid particles and encapsulation of liquid core. The technique has achieved limited success in the area of uniform core shell structure with liquid as core, as it requires matching of strict thermodynamic and kinetic factors. The interfacial te...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
