Modeling of Reversible Chain Transfer Catalyzed Polymerization by Moment Equations Method

A moment equations method was performed to study the Reversible chain Transfer Catalyzed Polymerization (RTCP) of styrene in 80°C. To do this, a kinetic scheme containing conventional free radical polymerization reactions and equilibrium reactions of RTCP was assumed. After obtaining mass balance equations, three moment equations were defined for free and dormant radicals and dead chains. M...

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...

Reversible addition-fragmentation chain transfer polymerization in microemulsion.

This tutorial review first details the uncontrolled microemulsion polymerization mechanism, and the RAFT polymerization mechanism to provide the necessary background for examining the RAFT microemulsion polymerization mechanism. The effect of the chain transfer agent per micelle ratio and the chain transfer agent aqueous solubility on the RAFT microemulsion polymerization kinetics, polymer mole...

Reversible addition fragmentation chain transfer (RAFT) polymerization from unprotected cadmium selenide nanoparticles.

Characterisation of nanoclay dispersion in resin transfer moulded glass/nanoclay/epoxy composites

A novel approach for characterisation of nanoclay dispersion in polymeric composites using electron microprobe analysis (EMPA) is presented. Dispersion analysis was performed on three sets of centre-gated discs fabricated by resin transfer moulding. The first set was neat epoxy polymer without reinforcement, whereas the second set comprised 17 vol.-% randomly oriented chopped glass fibre prefor...
