Self-polymerization is a phenomenon in which vinyl resins or vinyl monomers polymerize themselves under the influence of impurities such as heat, light or peroxides during storage, transportation, separation, and refining. Such as unsaturated polyester resin, styrene or acrylate monomer. In order to prevent the occurrence of self-polymerization, phenolic polymerization inhibitors can be added, protected from light, and stored in a cool place.
