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 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...

15 صفحه اولKinetics of ethylene polymerization over titanium-magnesium catalysts: The reasons for the observed second order of polymerization rate with respect to ethylene
The data on the effect of ethylene concentration on polymerization rate for several modifications of modern highly active titanium–magnesium catalysts TiCl4/MgCl2 are presented. These catalysts differ in titanium content and conditions of support preparation, activities, and the shape of kinetic curves. It is found that the observed order of polymerization rate with respect to ethylene in the r...
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], ...
