Suspension polymerization process used to make a number of thermoplastic polymers such as commercially widely used such PVC (polyvinyl chloride) and many other resins as well. Why the suspension polymerization process is used for? This method is only applicable to only water-insoluble monomers.The isolation of the product is very easy and the products are very pure.ĭisadvantages of the suspension polymerization.Since the water is used as a solvent this method is economical.Advantages of the suspension polymerization It requires a longer duration for higher conversion it is suitable for free radical and polycondensation polymerization. Isolation of the polymer or product becomes very easy as it involves only the filtration of beads and removal of surface-active agents or colloids by water washing the washed and dried product of polymer can be used for molding process and it can be dissolved in certain medium to be used as adhesive or coatings. Polymerization proceeds to a hundred percent conversion rate and the product are obtained as a spherical bead or pearl. Three types of PVC manufacture exist: suspension polymerisation, emulsion polymerisation and bulk (or mass) polymerisation. There will be a continuous aqueous phase that acts as an efficient heat transfer medium so it is exothermally well controlled. In this suspension polymerization process, the monomers are water-insoluble and polymerized monomers are suspended in the form of fine droplets over the solvent they are stabilized and prevented from coalescing by using suitable water-soluble colloids surface-active agents and by steering. What are the two types of the polymerization. ![]() What are the polymerization techniques?.What kind of the initiators are used in the suspension polymerization?.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water. Why the suspension polymerization process is used for? Emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomer, and surfactant.Disadvantages of the suspension polymerization.Advantages of the suspension polymerization This encapsulation strategy involves dispersion of polymeric solution loaded with lead into immiscible liquid phase at low pressure to form an emulsion.
