โœฆ Synopsis

The ,polymerisation of a vinyl monomer, which is promoted by an added free-radical generator. is considered. When the polymerisation occurs in a continuous-flow reactor, the dynamic behavior of the reactor is shown to depend on the generator concentration. Reactor stability can depend on the start-up procedure, In the case of styrene polymerisation, start-up procedures which are safe when initiation is purely thermal may be unsafe when a generator is present. The importance of small changes in physical properties of the reaction tluid is demonstrated and the behavior of monomers other than styrene is discussed. lNlRODUCTION Symbols are listed below. Recently, it has been shown that the dynamic behaviour of a con&uous-flow chemical reactor depends on the start-up procedure[l]. Predictions of dynamic behaviour were realistic only when allowance was
