Description
STH styrene for hromatogr. (3 ml)
C8H8 styrene (phenyl ethylene, vinyl benzene, etilenbenzol) — colorless liquid with specific smell. Styrene is almost water - insoluble, we will well dissolve in organic solvents, good solvent of polymers. Styrene belongs to the third (State standard specification 12.1.005 - 88) class of danger. Styrene easily is oxidized, attaches halogens, will be polymerized (forming firm vitreous weight — polystyrene) and copolymerized with different monomers. Polymerization happens already at the room temperature (sometimes to explosion) therefore at storage styrene is stabilized antioxidants (for example, tretbutilpirokatekhiny, hydrochinone). Halogenation, for example, in reactions with bromine, unlike aniline goes not on benzene ring, and on vinyl group with education (1,2 - dibrometit) benzene. Styrene is applied almost only for production of polymers. Numerous types of polymers on the basis of styrene vklyuchayutpolistirol, polyfoam (the made foam polystyrene), the polyethers modified by styrene, ABS plastics (acrylonitrile - butadiene - styrene) and SAN (styrene acrylonitrile). Also styrene is included into sostavnapalm.

The shaving from polystyrene dissolved in styrene forms ideal glue for polystyrene: under the influence of heat and the remains of polymerization reactors the adhesive line will quickly enough be polymerized and completely disappears, thus, 2 details turn into uniform monolith.
