Polystyrene has a long history of evolution behind it. In 1839, a German apothecary called Eduard Simon discovered polystyrene. Eduard Simon isolated the substance from natural resin, however, he did not know what he had discovered.
It took another German, organic chemist, Hermann Staudinger, to realize that Simon's discovery, comprised of long chains of styrene molecules, was a plastic polymer.
In 1922, Hermann Staudinger published his theories on polymers, stating that natural rubbers were made up of long repetitive chains of monomers that gave rubber its elasticity. He went on to write that the materials manufactured by the thermal processing of styrene were similar to rubber. They were the high polymers including polystyrene. In 1953, Hermann Staudinger won the Nobel Prize for Chemistry for his research.
Polystyrene was accidentally discovered in 1839 by Eduard Simon; an apothecary in Berlin, Germany. From storax, the resin of Liquidambar orientalis, he distilled an oily substance, a monomer that he named styrol. Several days later Simon found that the styrol had thickened, presumably due to oxidation, into a jelly he dubbed styrol oxide ("Styroloxyd").Polystyrene was accidentally discovered in 1839 by Eduard Simon; an apothecary in Berlin, Germany.

John Blyth and German chemist August Wilhelm von Hofmann showed that the same transformation of styrol took place in the absence of oxygen
. They called their substance metastyrol. Analysis later showed that it was chemically identical to Styroloxyd. In 1866 Marcelin Berthelot correctly identified the formation of metastyrol from styrol as a polymerization process. About 80 years went by before it was realized that heating of styrol starts a chain reaction, which produces macromolecules, following the thesis of German organic chemist Hermann Staudinger (1881 - 1965). This eventually led to the substance receiving its present name, polystyrene. The I.G. Farben Company began manufacturing polystyrene in Ludwigshafen, Germany, about 1931, hoping it would be a suitable replacement for die cast zinc in many applications. Success was achieved when they developed a reactor vessel that extruded polystyrene through a heated tube and cutter, producing polystyrene in pellet form.
Characteristics of Polystyrene:
Pure solid polystyrene is a colorless, hard plastic with limited flexibility. It can be cast into molds with fine detail. Polystyrene can be transparent or can be made to take on various colors. It is economical and is used for producing plastic model assembly kits, plastic cutlery, CD "jewel" cases, and many other objects where a fairly rigid, economical plastic of any of various colors is desired.
Polystyrene's most common use, however, is as expanded polystyrene (EPS). Expanded polystyrene is produced from a mixture of about 90-95% polystyrene and 5-10% gaseous blowing agent, most commonly pentane or carbon dioxide. Through the use of heat, usually stem, the solid plastic is expanded into foam.
Expanded polystyrene used to contain CFCs, but other, more environmentally safe blowing agents are now used. Because it is an aromatic hydrocarbon, it burns with an orange-yellow flame, giving off soot.

Styrofoam hasn't pH.

The Styrofoam was invented in 1941.
The first styrofoam cup was in the 1960s and it was invented by Mr. Dart. He is still alive living in the Cayman Islands
Foamed polystyrene, or Styrofoam, was discovered in 19541 by Ray McIntire. They rediscovered a method first discovered by Carl Munters.
Gottfried J. Schmidt, it was invented in the 1930's and sold by the Perfect Carton Opener Sales Corporation, Starrett Lehigh Building, 601 West 26th Street, New York City
yes, styrofoam can be alternative scented glue.. because,.. i read ina certain article.. that sony corporation.. alreaday proved it.. :)) !!...

Yes. Styrofoam is notorious for its static charge. This has killed people - in the 1960s the Air Force tried shipping a missile padded in Styrofoam, and the static charge caused the motor to ignite. (After that, the Air Force invented the pink plastic film many computer parts are now shipped in.)

This depends on what you are trying to use to dissolve the Styrofoam. Gasoline will dissolve Styrofoam. Water will not.
