Surface finish Suspension polymerization

The conducting of polymerization reactions in a solvent is an effective way to disperse heat in addition, solutions are much easier to stir than bulk polymerizations. Solvents must be carefully chosen, however, so that they do not imdergo chain-transfer reactions with the polymer. Because it can be difficult to remove solvent from the finished viscous polymer, solution polymerization lends itself best to polymers that are used commercially in solution form, such as certain types of adhesives and surface coatings. Polymerization of gaseous monomers is also conducted with the use of solvents, as in the production of polyethylene. Refer to Bulk Polymerization and Suspension Polymerization. 

In normal conditions, PMMA is a hard transparent material. Molecular weight is the main property determinant. High molecular weight PMMA can be manufactured by free radical polymerization (bulk, emulsion, and suspension polymerisation). Bulk polymerization is used for cast semifinish products (sheet, profiles and even tubes), and the cast polymer is distinguished by superior mechanical properties and high surface finish...
