Syndiotactic PS is back.Idemitsu Kosan Co. Ltd. of Japan has started to manufacture and sell syndiotactic A syndiotactic macromolecule in polymer chemistry is a tacticity essentially comprising alternating enantiomeric configurational base units which have chiral or prochiral atoms in the main chain in a unique arrangement with respect to their adjacent constitutional units. polystyrene (SPS (Standby Power System) A UPS system that switches to battery backup upon detection of power failure.

SPS is a clear, crystalline engineering thermoplastic made from ordinary styrene sty·rene n. A colorless oily liquid from which polystyrenes, plastics, and synthetic rubber are produced. Also called vinylbenzene. monomer monomer (mŏn`əmər): see polymer. monomer Molecule of any of a class of mostly organic compounds that can react with other molecules of the same or other compounds to form very large molecules (polymers). with a metallocene catalyst. It offers good heat and chemical resistance for automotive and electrical/electronic parts. Idemitsu offers around a dozen grades that are flame-retardant, glass-filled, platable, or alloyed with standard PS. Tel: (630) 681-8204 * PT Direct: 672CH |
