HazardIdentification (based on NFPA-704 M Rating System):Health 1, Flammability 2, Reactivity 0. Insoluble in water.Potential Exposure: Tumorigen,Mutagen, Human Data; Primary Irritant. Methylstyrene isused as an additive, a plasticizer, and as a copolymer; usedin the production of modified polyester and alkyd resinformulations.
Intermediate for ABS plastics, Styrene - Butadiene rubber, Polystyrene, Styrene - Acrylonitrile Resins, Perfumery, Polyalphamethyl Styrene, Polyester resins
Polymerization monomer, especially forpolyesters.
α-Methylstyrene is not a styrenic monomer in the strict sense. The methyl substitution on the side chain, rather than the aromatic ring, moderates its reactivity in polymerization. It is used as a specialty monomer in ABS resins, coatings, polyester resins, and hot-melt adhesives. As a copolymer in ABS and polystyrene, it increases the heat-distortion resistance of the product. In coatings and resins, it moderates reaction rates and improves clarity.
Tili ndi mafakitale apamwamba kwambiri omwe ali ndi mgwirizano wozama, omwe angakupatseni mankhwala apamwamba kwambiri komanso mitengo yampikisano. Ndipo titha kuperekanso kuchotsera pogula zinthu zambiri.Ndipo timagwirizana ndi makampani ambiri otumiza katundu, amatha kubweretsa zinthu mosatekeseka m'manja mwanu. Kutumiza nthawi ndi za 3-20 masiku chitsimikiziro cha malipiro.
