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.
Sinezimboni eziningi zekhwalithi ephezulu ngokubambisana okujulile, ezingakunikeza ngemikhiqizo yekhwalithi ephezulu namanani ancintisanayo. Futhi singanikeza izaphulelo zokuthenga ngobuningi.Futhi sibambisana nezinkampani eziningi ezichwepheshile zokudlulisa impahla, zingaletha imikhiqizo ngokuphepha nangokushelela ezandleni zakho. Isikhathi sokulethwa cishe yizinsuku ezi-3-20 ngemuva kokuqinisekiswa kwenkokhelo.
