Suspension polymerization - Wikipedia
Suspension polymerization is divided into two main types, depending on the morphology of the particles that result. In bead polymerization, the polymer is soluble in its monomer and the result is a smooth, translucent bead. In powder polymerization, the polymer is not soluble in its monomer and the resultant bead will be porous and irregular. [5]

Suspension polymerization technique: parameters affecting …
2019年4月4日 · Suspension polymerization may be classified into two types on the basis of polymer solubility in the monomer i.e. suspension bead and suspension powder polymerization (Fig. 4). An example of PS-co-DVB copolymer synthesis is presented to understand the synthesis mechanism of suspension polymerization, followed by the study of effect of various ...
In present review, suspension polymerization technique is highlighted in detail with control of particle size, advantages and its applications. The aim of the review is to understand the basics of suspension polymerization for the synthesis of polystyrene cross-linked with …
Suspension polymerization is particularly useful when the final polymer is required to be in the form of small “beads” (which often have the same size distribution as the drops from which they are formed). However, product contamination can be a …
