Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. [5] Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low ...
In 1865, the German chemist Emil Erlenmeyer found that styrene could form a dimer, [14] and in 1866 the French chemist Marcelin Berthelot stated that "metastyrol" was a polymer of styrene (i.e. polystyrene). [15] Meanwhile, other chemists had been investigating another component of storax, namely, cinnamic acid.
Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3.It is a highly flammable, colorless liquid with an odor similar to that of gasoline.This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material.
The eight most common types of synthetic organic polymers, which are commonly found in households are: Low-density polyethylene (LDPE) High-density polyethylene (HDPE) Polypropylene (PP) polyethylene (PP) Polyvinyl chloride (PVC) Polystyrene (PS) formaldehyde. Nylon, nylon 6, nylon 6,6; Teflon (Polytetrafluoroethylene) Thermoplastic ...
Skeletal structure of polystyrene. Polystyrene is a synthetic hydrocarbon polymer that is widely adaptive and can be used for a variety of purposes in drug delivery. These methods include polystyrene microspheres, nanoparticles, and solid foams. In the biomedical engineering field, these methods assist researchers in drug delivery, diagnostics ...

This fallen angel was the worst-performing stock in the S&P 500 in 2024. This huge drugstore chain is a safe retail play, paying a huge 10.85% dividend, which was cut almost half this time last ...
The vast majority of hydrocarbons found on Earth occur in crude oil, petroleum, coal, and natural gas. For thousands of years they have been exploited and used for a vast range of purposes. [12] Petroleum (lit. ' rock oil ') and coal are generally thought to be products of decomposition of organic matter. Coal, in contrast to petroleum, is ...
