Isodesmic Supramolecular Assembly of Phenylethynylene Bis‐Urea Macrocycles
Chemistry – A European Journal, EarlyView.A soluble phenylethynylene bis‐urea macrocycle assembles in polar media via an isodesmic hydrogen bonded mechanism. Spectroscopic and morphological studies reveal nanoscale aggregates with short chain length, while guest additives modulate enthalpy and polymerization, demonstrating tunable supramolecular assembly.

PNEUMOTOXICITY AND HEPATOTOXICITY OF STYRENE AND STYRENE OXIDE
Journal of Toxicology and Environmental Health, 1996The purpose of this study was to investigate the toxicity of styrene and styrene oxide in the lung in comparison to the toxicity in the liver. Pneumotoxicity caused by styrene or styrene oxide was measured by elevations in the release of gamma-glutamyltranspeptidase (GGT) and lactate dehydrogenase (LDH) into bronchoalveolar lavage fluid (BALF), while ...

Mutagenicity of styrene and styrene oxide
Mutation Research, 1977Abstract Incubation of S. typhimurium strain TA 1535 with styrene increased the number of his + revertants/plate in presence of a fortified S9 rat-liver fraction. Styrene was also highly cytotoxic for Salmonella cells. Styrene oxide, the presumed first metabolite, had a mutagenic effect towards strains TA 1535 and TA 100 both with and without ...

Toxicity of styrene and styrene oxide on chick embryos
Toxicology, 1977Styrene and styrene oxide were injected into the air space of fertilized chicken eggs at different times during an incubation period of 14 days. The toxicity of styrene and styrene oxide when injected on the fourth day of incubation revealed an LD50 of 40 mumol/egg and 1.5 mumol/egg, respectively.

Mutagenic effects of styrene and styrene oxide
Mutation Research/Genetic Toxicology, 1979Abstract Styrene and its presumed metabolite styrene oxide were tested in the Salmonella/liver-microsome test on the tester strains TA1535, TA1537, TA1538, TA98 and TA100 of Salmonella typhimurium . Styrene oxide, in the concentration range 1–10 μmoles per plate, was mutagenic on TA1535 and TA100, both in the absence and the presence of a rat-liver ...

Styrene dibromide as a photoinitiator in the polymerization of styrene
Transactions of the Faraday Society, 1970The polymerization of styrene, photoinitiated with small amounts of (1,2-dibromoethyl)-benzene (styrene dibromide), has been studied at 30°C. Rates of initiation and of consumption of styrene have been estimated, and molecular weights have been determined by gel permeation chromatography.

Abstract Styrene is a colorless to slightly yellow, oily liquid that spontaneously polymerizes unless inhibited. At low concentrations, it has a sweet odor; at concentrations above 100 ppm, it is objectionable. Styrene is widely used to make polystyrene, copolymers with acrylonitrile and butadiene, styrene polyesters, and other resins

Styrenics: polystyrene and styrene copolymers
1998The first modification of rubber by incorporation of polystyrene (PS) is credited to Francis Edward Matthews, who during the years 1911-1913 (Figure10.1) received several international patents for the manufacture of lacquers and ‘articles that are normally made of hard rubber, celluloid, vulcanite, ebonite, glass, wood and similar materials’.

Carbocationic Polymerization: Styrene and Substituted Styrenes
1989Although the cationic polymerization of styrene and substituted styrenes (referred to here collectively as ‘styrenes’) belongs to one of the oldest and most studied polymerization systems, it is not yet completely understood. In this chapter we shall try to review selectively and critically the existing literature on the cationic polymerization of ...
