Application

ALPHA-METHYL STYRENE is a monomer with inherent advantages of stability and handling over styrene. It copolymerises with other monomers to give better end-products.
ALPHA-METHYL STYRENE exhibits very little tendency to polymerise with thermal or free radicals, but readily polymerises with ionic catalyst to give polymers from liquid to solid having a wide range of properties which are useful in PVC processing and surface coating industries.
ALPHA-METHYL STYRENE copolymerises with other monomers like Styrene, Divinyl Benzene, Acrylates, Acrylontrile, Butadiene etc. It improves heat distortion properties of ABS plastics, Polystyrene, MMA, SAN etc.
ALPHA-METHYL STYRENE copolymerises by emulsion technique with Butadiene to give a good quality synthetic rubber.
ALPHA-METHYL STYRENE finds application in various other end-products like perfumery chemicals, antioxidants, drying oils, lubricating oils, alkyd resins, modified phenolic resins etc.
Low molecular weight polymers of ALPHA-METHYL STYRENE are viscous liquids that they are used as plasticizers in paints, waxes, adhesives and plastics.
