Suspension Polymerization of HPMC

In the production of synthetic resins such as polyvinyl chloride (PVC), polyvinylidene chloride and other copolymers, suspension polymerization is most commonly used and it is necessary to stabilize the hydrophobic units suspended in water. As a water-soluble polymer, HPMC product has excellent surface activity and acts as a colloid protective agent, which can effectively prevent the aggregation of polymer particles. Furthermore, HPMC, despite being a water-soluble polymer, is also somewhat soluble in hydrophobic units and increases the unit porosity of the produced polymeric particles, and it provides the polymer with good removal of residual units and enhanced Ability to absorb plasticizers.
