About EMULSION POLYMERIZATION SET-UP APPARATUS

Specification:

EMULSION POLYMERIZATION SET-UP APPARATUS

The set-up is used to carry out theemulsion polymerization involving the polymerization of an unsaturated monomerlike Styrene.

The emulsion is of the type: oil inwater, the monomer is oil soluble & the initiator is water-soluble & anemulsifier is used to create a stable emulsion.

Apparatus can be used to generate thekinetic data for emulsion polymerization under various operating conditionslike temperature, emulsifier concentration, etc.

Polymerization is carried out underthe atmosphere of air-free nitrogen. The set-up consists of a jacketed type SSreactor fitted with a variable speed agitator & baffle.

Hot water from a digitally controlledwater bath is circulated in the jacket using a pump.

Metered quantity of nitrogen gas froma cylinder passes through a de-oxygenation column & allowed to enter thereactor.

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

Initiator from the reservoir issupplied to the reactor under pressure. Set-up is complete & self-containedwith sampling ports
