Difference Between Styrene and Polystyrene
ثبت نشده
چکیده
Styrene and polystyrene are two important organic compounds with a wide range of applications. The key difference between styrene and polystyrene is that it is the polymerization of styrene that forms polystyrene, a synthetic thermoplastic elastomer. Styrene is chemically called vinyl benzene and is among one of the oldest known vinyl compounds in the world. This aromaticcompound was first isolated from certain natural resins in 1839. Later in the 1930s, chemists were able to produce polystyrene in commercial scale by addition polymerization of styrene monomer units. Polystyrene became one of the most widely used plastics, especially during the World War II. Even today, styrene and polystyrene play some important roles in the polymer industry owing to their characteristic physical and chemical properties.

The Effect of Microwave on Migration of Styrene Monomer Polystyrene Food Packaging and Compared to other Thermal Processes
The migration of packaging material constituents into food is a product of the interaction between the food and packaging material. This phenomenon is of importance because some migrating substances may be toxicologically carcinogenic and endanger the consumer safety. Polystyrenes are used in many food-contact applications for the packaging of aqueous-based, fatty and dry foods. The correlation...

Abstract As a monomer, the [N-(alanine)] para-styrene sulfonamide (ASS) was prepared, from the reaction of para-styrene sulfonyl chloride and (S)-(+)-alanine in the presence of KOH 1M as a base, and CH3Cl was used as solvent. The monomer confirmed using FT-IR and 1H-NMR spectroscopy. Polystyrene [N-(alanine) sulfonamide] (PASS) was also prepared from the polymerization of [N-(alanine)] pa...
متن کاملUV absorption spectra of polystyrene
Polystyrene (PSt) exhibits a new UV absorption band at around 290nm in comparison with ethylbenzene, which is attributed to associative interaction between pendant phenyl groups, similar absorption bands are also observed for polymers of styrene derivatives. The UV spectra suggest charge-transfer complex formation between the polymeric and monomeric donors with electron-acceptor tetracyanoethyl...
