Pronunciation

  • /pɒliˈstaɪriːn/[1]

Etymology

It is formed from English poly- + styrene,[2][3][4][5][6] because the substance is a polymer of the liquid hydrocarbon styrene.[7][2] The name of the hydrocarbon, recorded from 1885, is formed from the stem of styrax, the storax tree from whose resin it was first obtained, and the suffix -ene.[2][7][8] The tree's name comes through Latin from a Greek word that Etymonline considers of Semitic origin.[7] Compare French polystyrène, recorded from 1936 or earlier.[2]

Earliest recorded meaning

A polymer of styrene, especially a hard thermoplastic resin: 1927, in an article by G. S. Whitby in the India-Rubber Journal.[2][3] Etymonline dates the word to 1922.[7]

Semantic evolution

The word was first a chemists' name for the polymer, especially the hard, colourless resin.[2][7] It soon came to cover the plastics made from it, which are used as light rigid foams, as moulding materials and as films.[2][4] The white foam, expanded polystyrene, is used for insulation and packing, and the clear, glassy form for light fittings and water tanks.[9] From 1938 the short form styrene was also used for the plastic.[2][4]
