Bulk polymerization or mass polymerization is carried out by adding a soluble radical initiator to pure monomer in liquid state. The initiator should dissolve in the monomer. The reaction is initiated by heating or exposing to radiation. As the reaction proceeds the …

Bulk polymerization, which may also be referred to as mass polymerization, involves a monomer and an initiator as the main components, without a solvent. The polymerization conforms to the fixed shape of the reaction vessel when solidification occurs.

Bulk polymerization is carried out in the absence of any solvent or dispersant and is thus the simplest in terms of formulation. It is used for most step-growth polymers and many types of chain-growth polymers.

In this laboratory, you will analyze the free radical polymerization kinetics of styrene. In addition, you will prepare simple polymers from another monomer, butyl methacrylate. All of these polymerizations will be initiated using benzoyl peroxide as the radical initiator.

Bulk (Mass) Polymerization • Carried out to high conversion • Free radical kinetics apply • Used for ethylene, styrene, methyl methacrylate Advantages: • Minimum contamination of product General Description: Monomer Initiator

Bulk polymerization is used in the free radical polymerization of methyl methacrylate (H 2 C=C(CH 3)COOCH 3) or styrene (H 2 C=CHC 6 H 5) to get transparent powders of PMMA or polystyrene (thermocole) and also the cast sheets of poly vinyl chloride (PVC). Emulsion polymerization: In this type the monomer is dispersed in aqueous phase as emulsion.

Bulk Polymerization Standard Operating Procedure (SOP) By Devin Roach What is bulk polymerization?: Bulk polymerization is a common method for polymer fabrication on an industrial scale. In general, the initial material consists of mostly of pure monomer. Initiator is then added and the reaction begins upon exposure to heat or other free energy.

So there two main methods, solution and bulk polymerization respectively. i .Bulk Polymerization : This method involves only the monomer molecule, an initiator and a chain transfer agent ( if necessary). The monomer is taken in the liquid state and the initiators is …
