Chemical Properties clear colourless liquid
Chemical Properties Methylstyrene is a colorless liquid with a characteristic odor.
Physical properties Colorless liquid with a sharp aromatic odor. Odor threshold concentration is 290 ppb (quoted, Amoore and Hautala, 1983).
Uses Intermediate for ABS plastics, Styrene - Butadiene rubber, Polystyrene, Styrene - Acrylonitrile Resins, Perfumery, Polyalphamethyl Styrene, Polyester resins
Uses Polymerization monomer, especially forpolyesters.
Uses 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.
