What is alpha methyl styrene used for?
Alpha-methylstyrene (AMS) is a colourless liquid used as a co-monomer in a range of polymerization processes to improve impact and heat resistance. The primary use of AMS is in acrylonitrile-butadiene-styrene (ABS)resin but it is also used in adhesives, resins, printing ink, tackifier.
Is alpha methyl styrene toxic?
Strong eye and nasal irritation has been noted at concentrations above 600 ppm [Gerarde 1960; Wolf et al. 1956]. Basis for revised IDLH: The revised IDLH for a-methyl styrene is 700 ppm based on acute toxicity data in humans [Wolf et al.
Is alpha methyl styrene flammable?
ICSC 0732 – alpha-METHYL STYRENE. Flammable. Above 54°C explosive vapour/air mixtures may be formed. NO open flames, NO sparks and NO smoking.
What is the chemical formula of cumene?
C9H12Cumene / Formula
What is the signal word for acetone?
Signal Word: DANGER! H225 Highly flammable liquid and vapor. H319 Causes serious eye irritation.
What is styrene polymer?
Polystyrene (PS) /ˌpɒliˈstaɪriːn/ is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight.
Is styrene a plastic?
What is Styrene (Polystyrene)? High Impact Polystyrene (HIPS), often referred to as styrene, is an easily machined and fabricated impact-resistant, versatile, and economical plastic.
What is cumene used for?
Cumene, also known as isopropylbenzene, 2-phenylpropane or (1-methylethyl) benzene, is widely used as a chemical intermediate in the production of phenol and acetone. Cumene is also used as a thinner for paints, lacquers, and enamels and it is a natural component of coal tar and petroleum.
What is cumene made of?
Cumene is produced from the distillation of coal tar and petroleum fractions or by the alkylation of benzene with propene using an acidic catalyst. It is used almost exclusively to produce phenol and acetone. Cumene occurs naturally in crude oil, and is found in the environment in plants and foodstuff.
What is Section 1 of the safety data sheet alpha-methylstyrene?

What is the best way to store alpha methyl styrene?
Alpha-methyl styrene should be stored away from heat, oxidizers, peroxides, halogens, catalysts for vinyl or ionic polymers, aluminum, and iron chloride. For small spills of alpha-methyl styrene, take up with sand or other noncombustible absorbent and place into containers for later disposal.
What is the polymerization of α-methylstyrene?
The polymerization of α -methylstyrene has been experimentally studied by Greer and coworkers [79]. Poly ( α -methylstyrene) is a fully flexible linear polymer chain joined by covalent bonds.
What is alpha methylstyrene used for?
As a copolymer with methylmethacrylate, alpha-methylstyrene is resistent to distortion at high temperatures and is used in food applications (2). Polymers of alpha-methylstyrene possess low molecular weights and are viscous liquids that are employed as plasticizers in plastics, paints, waxes and adhesives (2).
