Quantitative analysis of styrene monomer in polystyrene and foods including some preliminary studies of the uptake and pharmacodynamics of the monomer in rats.

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...

Studies of Migration of Styrene Monomer from Polystyrene Packaging into the Food Simulant

تعیین انتقال مونومراستایرن از ظروف پلی استایرنی شفاف به نوشیدنیهای داغ

Polystyrene plastic material is a part of important packaging materials that is widely used. In recent decades, It is excessively applied in manufacturing of disposable drinking containers. Temprature is an important factor in determination the stability styrene monomer. The migration of styrene monomer in to hot drinks may cause chronic toxic effect in nervous system, liver and other organ of ...

Polystyrene Supported [N-(Alanine) Sulfonamide]/Palladium Chloride: Synthesis, Characterization, for Heck Coupling Reactions

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...

Preparation and Characterization of Polystyrene-Silver NanocompositeUsing MicroemulsionMethod and its Antibacterial Activity

Polymer nanocomposites containing metals have been used in a wide range of applications due to their versatility, and tunable characteristics including physical, chemical, biological and mechanical properties. In this research work polystyrene-silver nanocomposite has been produced using polymerization of a w/o microemulsion system. Styrene monomer was used as the oil or continues phase of the ...
