Polyvinyl chloride (PVC) is one of the two most used polymers throughout the world due to its versatility, durability and relatively low cost. PVC production involves a complex polymerization process, which can be carried out by different methods, including suspension, emulsion and mass polymerization. Among these methods, suspension polymerization is most common, being responsible for about 80% of the world's PVC production. In this process, an essential component is the suspending agent , whose function is vital to guarantee the quality of the final product. PVC suspending agent
