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.
متن کاملPhotoinitiated 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...
متن کاملMicroemulsion polymerization of styrene in the presence of macroinimer
The kinetics of o/w electrostatically and sterically-stabilized microemulsion polymerization of styrene with and without macromonomeric azoinitiator (macroinimer; MIM) have been investigated. The microemulsion polymerization stabilized by the ionic emulsifier sodium dodecyl sulfate (SDS) or the non-ionic emulsifier Tween 20 (Tw 20) was initiated by ammonium peroxodisulfate (APS)/sodium thiosulf...
متن کاملKinetics of styrene emulsion polymerization in the presence of montmorillonite
The effect of the pristine sodium montmorillonite (Na-MMT) on the styrene emulsion polymerizations with different concentrations of SDS ([SDS]) was investigated. At constant [SDS], the polymerization rate is faster for the run with 1 wt.% Na-MMT compared to the counterpart without Na-MMT. Micelle nucleation predominates in the polymerizations with [SDS] = 13 mM. On the other hand, the contribut...
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...
