Monomers: Identity: . Ethenylbenzene Synonym: Styrene CAS No.: 100-42-5 Weight percentage: 76.8% Identity: . 2-Propenoic acid, butyl ester Synonym: Butyl acrylate CAS No.: 141-32-2 Weight percentage: 22.9% Identity: . Diethenylbenzene Synonym: Benzene, divinyl CAS No.: 1321-74-0 Weight percentage: 0.3% Maximum content of residual monomers: <0.2% (w/w) PHYSICAL AND CHEMICAL PROPERTIES Styrene acrylate copolymer consists of fine white beads at room temperature and atmospheric pressure. Its physical and chemical properties include: Glass-transition temperature: 56.7-64.8°C Vapour pressure: negligible; the chemical is a cross-linked polymer Water solubility: negligible; the chemical is cross-linked polymer Explosion potential: this material, like most organic materials in powder form, is capable of creating a dust explosion Reactivity: incompatible with strong oxidisers Particle size distribution: range: 63-116 microns The notifier has justified the lack of test results for hydrolysis, partition coefficient and soil adsorption on the grounds that the notified substance is a high molecular weight, linked polymer with negligible vapour pressure and water
