Tromsdorf effect

This leads to high adiabatic temperature rises, which lie in the range of 250-1,800 K. Furthermore, instantaneous increases of the reaction rate and hence the thermal power are possible. This is known as the gel or Tromsdorf effect. [Pg.90]

The Tromsdorf effect, also called the Norrish effect or gel effect, is associated with exothermic reactions during bulk polymerization. Autoacceleration of the polymerization rate can occur with medium to high polymerization conversions. This phenomenon inhibits termination. Strength of the Tromsdorf effect is calculated as the gel effect index [12]... [Pg.14]

The Tromsdorf effect can occur in suspension polymerization of PVC, but it is not as significant as it is with bulk polymerization. [Pg.14]
