EMULSION POLYMERIZATION SET-UP APPARATUS

Product Description

The set-up is used to carry out the emulsion polymerizationinvolving the polymerization of an unsaturated monomer like Styrene.

The emulsion is of the type: oil in water, the monomer isoil soluble & the initiator is water-soluble & an emulsifier is used tocreate a stable emulsion.

Apparatus can be used to generate the kinetic data foremulsion polymerization under various operating conditions like temperature,emulsifier concentration, etc.

Polymerization is carried out under the atmosphere ofair-free nitrogen. The set-up consists of a jacketed type SS reactor fittedwith a variable speed agitator & baffles.

Hot water from a digitally controlled water bath iscirculated in the jacket using a pump.

Metered quantity of nitrogen gas from a cylinder passesthrough a de-oxygenation column & allowed to enter the reactor.

Air has to be evacuated using a vacuum pump to create avacuum of up to 30mm of Hg before passing the nitrogen supply.

Initiator from the reservoir is supplied to the reactorunder pressure. Set-up is complete & self-contained with sampling ports
