Chronic Toxicity and Three-Generation Reproduction Study of Styrene Monomer in the Drinking Water of Rats. BELILES, R. P., BUTALA, J. H., STACK, C. R., AND MAKRIS, S. (1985). Fundam. Appl. Toxicol.. 5,855-868. Chronic toxicity and reproductive performance were evaluated in groups of rats receiving styrene monomer in their drinking water at nominal concentrations of 0, 125, or 250 ppm. Fifty mal...

Tris-(benzyltriazolylmethyl)amine (TBTA) has been immobilized onto a styrenic monomer and subsequently copolymerized with styrene to afford catalytically active and reusable copolymers for the CuAAC reaction.

the increasing use of styrene, for the production of thermoplastics and rubbers, has given a special importance to this vital materialin petrochemical industries. more than 95 per cent of styrene production in the world is by dehydrogenation of ethylbenzene. present styrene production units are basically designed on the basis of 1940s units. producing countries and related research centres have...

A detailed model was developed for the emulsion copolymerization of styrene and MMA to predict the evolution of the particle size distribution (PSD) and molecular weight distribution (MWD) over the entire range of monomer conversion. A system exhibiting zero-one kinetics was employed. The model was used to optimise the emulsion copolymerization process in order to maximize particle size polydis...

The first radical polymerisation of styrene in porous coordination polymers has been carried out, providing stable propagating radicals (living radicals), and a specific space effect of the host frameworks on the monomer reactivity is demonstrated.

Styrene is discharged particulary from the factories of styrene resin and synthetic rubber, and it was listed as one of the offensive odor substances by the Offensive Odor Control Law in Japan at 1976. Styrene vapor has stimulating action on eye (STEWART et al. 1968) and membrana of nose and trachea (STEPHENSON & FOSDICK 1960). It has toxic effects on blood cells and liver (KATZ 1962), and nerv...

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...

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 isol...
