Acrylates.
ACRYLATES HAVE been around since the 1930s, when Rohm and Haas began mass production of Plexiglas, a clear and resistant glass substitute made of polymerized methacrylate. It is used extensively for windowpanes, airplane canopies, car lights and windshields, streetlamps, and so on. Numerous other acrylates have been synthesized and have found applications in paints and adhesives, dental composi...
متن کاملLiquid Crystalline Acrylates and Their Polymers
In previous papers (1,2) the thermotropic properties and the kinetics of the bulk polymerization of the mesomorphic monomer cholesteryl acrylate have been described. In addition to cholesteryl acrylate, the methacrylate was prepared, as well as the respective acrylic methacrylic acid ester of cholestanol. We now wish to report the properties of these monomeric esters and the results of their po...

این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
15 صفحه اولRelative developmental toxicities of acrylates in rats following inhalation exposure.
The developmental toxicities of seven acrylates were studied in Sprague-Dawley rats after inhalation exposure for 6 h/day, during days 6 to 20 of gestation. The exposure concentrations were: for acrylic acid, 50, 100, 200, or 300 ppm; for methyl acrylate, 25, 50, or 100 ppm; for ethyl acrylate, 25, 50, 100, or 200 ppm; for butyl acrylate, 100, 200, or 300 ppm; for ethylhexyl acrylate, 50, 75, o...

BACKGROUND Acrylates are used in a wide variety of products such as solvents, adhesives, paints, printing ink, soft contact lenses, porcelain nails, and methacrylates (used by dentists and orthopedists). Currently there are various types of acrylic compounds: acrylates, cyanoacrylates (such as tissue adhesives and home glues), and methacrylates (prostheses and dental and orthopedic fillings). T...
