A Single Particle Growth Model in Styrene Coordination Polymerization

Dynamic Evolution of Droplet/Particle Size Distribution in Suspension Polymerization of Styrene

Gold-promoted styrene polymerization.

Styrene can be polymerized at room temperature in the presence of equimolar mixtures of the gold(III) complexes (NHC)AuBr3 (NHC = N-heterocyclic carbene ligand) and NaBAr'4, in the first example of a gold-induced olefin polymerization reaction.

Polymerization of propylene in a minireactor: Effect of polymerization conditions on particle morphology

Gas phase polymerization of propylene was carried out in a semi-batch minireactor using a commercially supported Ziegler–Natta (ZN) catalyst. The influence of variables including monomer partial pressure, external electron donor, reaction temperature and time on the particle morphology and size distribution was investigated. Generally, more uniform fragmentation and particle densities were obta...

Photoinitiated Polymerization of Styrene in Microemulsions

Photoinitiated polymerization of styrene in oil/water microemulsions has been successfully performed by using dibenzyl ketone (DBK) as initiator. The system remains transparent during the whole polymerization process. The molecular weights of polymers produced are in the order of IO5, and the polydispersity indexes (PDI) are in the range 1.6-2.2. The particle sizes of the latexes produced are i...

the effects of temperature, initiator and stabilizer on polymer particle size in suspension polymerization of styrene

in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...
