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...
متن کاملtricalcium phosphate containing sodium hexametaphosphate as polymer suspension stabilizer
tricalcium phosphate as hydroxyapatite is used as a suspension stabilizer in styrene polymerization process. particle size of tcp plays an essential role in the particles’ size distribution and geometrical form of polystyrene products. as the particle size of tcp is reduced, there will be much better chance to engulf the styrene particles. the higher the number of tcp particles surrounding each...
متن کاملPreparation of cassava starch grafted with polystyrene by suspension polymerization.
Cassava starch grafted with polystyrene (PS-g-starch) copolymer was synthesized via free-radical polymerization of styrene by using suspension polymerization technique. Potassium persulfate (PPS) was used as an initiator and water was used as a medium. The graft copolymer was characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermal gravimetric analysi...
متن کاملPreparation and Properties of Branched Polystyrene through Radical Suspension Polymerization
Radical solvent-free suspension polymerization of styrene with 3-mercapto hexyl-methacrylate (MHM) as the branching monomer has been carried out using 2,2′-azobisisobutyronitrile (AIBN) as the initiator to prepare branched polymer beads of high purity. The molecular weight and branching structure of the polymers have been characterized by triple detection size exclusion chromatography (TD-SEC),...
متن کامل281e Kinetic Modeling of the Vinyl Chloride Suspension Polymerization
The physical properties of the polymer product determine to a large extent its processability and applications. A large number of properties are directly related to the molecular mass distribution (MMD) of the polymer product. Besides the MMD, the polymer microstructure also plays an important role and influences to a large extent the thermal stability of the polymer product. Most of the therma...
