A general analysis of pseudostationary polymerization kinetics in the absence of chain transfer is presented. In the course of the treatment, a set of "higher order" pseudostationary conditions is established and it proves to be extremely helpful in dealing with degrees of polymerization. It is foun

✦ Synopsis
The polymerization behaviour of a typical spiro-orthoester, 2-Phenoxymethyl-l,4,6-trioxa-spirol4,4)-nonane, was investigated. The polymerization rate decreases abnormally with conversion; the effect is explained by a mechanism involving deactivation of the active centres by the polymer.

A kinetic modeling study was conducted for the Ziegler-Natta polymerization of butadiene with cobalt octoate/DEAC/water catalyst. The model equations for the single and dual active site models were analytically solved, and the closed-form expressions for conversion and both number and weight average
A major contribution to interpretations of biological organization in terms of chemical kinetics was that of Kacser (1957Kacser ( , 1960)). He started from an awareness that living organisms have ''systemic properties'' which depend on organization and functional relationships and so are not simply
An experimental investigation of the kinetics of the bulk free radical polymerization of butyl acrylate initiated with 2,2'-azobisisobutyronitrile ( AIBN ) was conducted at 50" and 60°C using two initiator concentrations. Conversion levels were measured by gravimetry and were independently confirmed
