Polystyrene copolymers are also produced; these contain one or more other monomers in addition to styrene. In recent years the expanded polystyrene composites with cellulose [39] [40] and starch [41] have also been produced. Polystyrene is used in some polymer-bonded explosives (PBX). [citation needed]
Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2.Its structure consists of a vinyl group as substituent on benzene.Styrene is a colorless, oily liquid, although aged samples can appear yellowish.

McDonald's (MCD) has finally made a move to revolutionize its ubiquitous cup. It's testing ways to finally ditch the foamy polystyrene cups that have accompanied the company's McFare for ages. The ...
[1] [2] Expanded polystyrene is used to manufacture foam cups, [3] and polypropylene is used to manufacture plastic cups. [4] As they are produced for single use, disposable cups and other similar disposable products constitute a major source of consumer and household waste, [5] such as paper waste and plastic waste. It has been estimated that ...
Expanded polystyrene foam (EPS or "styrofoam", white) is used in making insulation and packaging materials, such as the "peanuts" and molded foam used to cushion fragile products. Polystyrene copolymers are used in the manufacture of toys and product casings.
While bisphenol A (BPA) — a chemical that was commonly used in the lining of many metal food and drink cans, lids and caps — is no longer present in the packaging for most products (think ...
Discarded polystyrene cup on the shore of Lake Michigan. In the late 20th and early 21st century, there has been a global movement towards the phase-out of polystyrene foam as a single use plastic (SUP). Early bans of polystyrene foam intended to eliminate ozone-depleting chlorofluorocarbons (CFCs), formerly a major component.
