Ein automatisches dilatometer für versuche zur polymerisationskinetik

A dilatometer is described which does automatically the following work essential in kinetic investigations of polymerizations: Registering and plotting of the volume contraction of the sample (proportional to conversion) as a function of time, differentiation of the conversion-time curve and logarithmic plotting of the resulting rate of polymerization against time. Some examples are given to demonstrate the efficiency of the experimental set-up.
