The Kinetics of Polymerization
A comprehensive review is presented on the kinetics of polymerizations, as a summary of the studies on the polymerization kinetics performed in the authors' laboratory. Polymerizations were in the first place classified into several classes according to the relative magnitude of the rates of the elementary steps. The specific features of the kinetics were discussed by classifying into four main...
متن کاملSynthesis of Silica/Polystyrene Nanocomposite Particles by Miniemulsion Polymerization
Miniemulsion polymerization is one of heterogeneous polymerization method that can be effectively used to synthesis of various novel organic-inorganic nanocomposite particles. This method can provide opportunity of good incorporation between the polymer and inorganic phases in the formed submicrometer-sized particles. In this article, we report preparation polystyrene/silica nanocomposite p...
متن کاملThermodynamics and Kinetics of Ring - Opening Polymerization
Cyclic monomers that have been polymerized via ring opening encompass a variety of structures, such as alkanes, alkenes, compounds containing heteroatoms in the ring: oxygen [ethers, acetals, esters (lactones, lactides, and carbonates), and anhydrides], sulfur (polysulfur, sulfi des and polysulfi des), nitrogen [amines, amides (lactames), imides, N carboxyanhydrides and 1,3 oxaza derivatives], ...
متن کاملThe kinetics of actin nucleation and polymerization.
The polymerization kinetics of rabbit skeletal muscle actin was studied by following the increase in fluorescence of tracer amounts of actin conjugated to N-pyrenyl iodoacetamide. The observed polymerization kinetics could be precisely fit by numerical integration of equations describing a nucleation-elongation process. Under all conditions tested, the rate of nucleation was proportional to the...
متن کاملIN SITU SILICA SUPPORTED METALLOCENE CATALYSTS FOR ETHYLENE POLYMERIZATION
Bis(2-R-ind)ZrCl2 (R: H or phenyl) was supported on different types of silica by in situ impregnation method and used for ethylene polymerization. In this method, the step of catalyst loading on support was eliminated and common alkyl aluminum (triisobutylaluminum, TiBA) cocatalyst was used instead of expensive methyl aluminiumoxane (MAO) cocatalyst in the polymerization. The effect of surface ...
