✦ Synopsis

Flocculated and non-flocculated coal samples have been tested in a specially designed drier that can be operated under a relatively wide range of experimental conditions. Results obtained with a highly efficient reagent used in sedimentation tests of coal suggest a significant influence of additives on drying equilibrium and kinetics.

## Abstract The kinetics of the anionic ring‐opening polymerization of the DD~NMe~ cyclodisilazane, initiated by benzyllithium, has been investigated in different experimental conditions. In non‐polar solvents, the active centers are aggregated ion pairs which are in equilibrium with a small amount
