Methyl methacrylate is only one of a family of monomers, including the various esters of acrylic, methacrylic, and ethacrylic acids, which are polymerized to produce the thermoplastic resins known as the acrylates. A wide variety of reactions and starting materials may be utilized for their production however, the principal commercial product is polymethyl methacrylate, sold by Du Pont and Rohm Haas under the trade names of Lucite and Plexiglas, respectively. These materials were introduced to the United States market in 1936 (44) and have received widespread acceptance due principally to their outstanding optical properties. Production in 1949 was reported as about 22,000,000 to 25,000,000 pounds and peak wartime capacity was above30,000,000 pounds. While this can account for only about 2% of the current production of propylene for chemical purposes, the acrylate resins are of considerable commercial importance as they are sold at a relatively high price and are the only materials available that will meet the requirements for certain military and civilian products. [Pg.318]

Of a more specialized nature and on a company level are the prospectuses and registrations reported to the Securities and Exchange Commission. All are within the public domain and are available to all at the offices of the commission. The information is entirely reliable and will vary from complete descriptions of the operations of a corporation and plans for the future to rather cryptic and nebulous statements from the viewpoint of chemical interest. Often operations are noted for the first and only time in these documents. The Rohm Haas Co. prospectus is a case in point. [Pg.124]

There are recent literature reports according to which alcohols and aldehydes dehydrogenate in the presence of ammonia to form nitriles. Process are operated by Rohm Haas, Ruhrchemie, and Bayer [21-23]. Molybdenum nitrides were found most efficient as heterogeneous catalysts [15] cf. eqs. (8) and (9) (R = n-CsHv). They also effect dehydrogenation of amines, as demonstrated for -butylamine in eq. (10). [Pg.1301]

There are many adsorbents available in the market. Rohm Haas, to name one vendor, supplies the Amberlite class of adsorbents, which includes Amberlite XAD-4, ZAD-7, XAD-7HP, ZAD-16, and XAD-1180 [169]. These nonfimctionalized materials are reported to adsorb chlorinated solvents, herbicides, nonaromatic compounds, and aromatic species, among many others. A typical example is the use of XAD-7 to remove phenolics from brine. Another class of adsorbents is the Ambersorb series. Ambersorb 572 is claimed to remove quaternary ammonium salts such as chloromethyl tetraethyl ammonium ions from brine [171],... [Pg.655]

Vinylidene chloride monomer is produced commercially in the United States by The Dow Chemical Co. and PPG Industries. The monomer is produced in Europe by Imperial Chemical Industries, Ltd. and Solvin. The monomer is produced in Japan by the Asahi Chemical Co., Kureha Chemical Industries, and Kanto Denka Kogyo Co. Commercial suppliers of VDC copolymers include The Dow Chemical Co. in the United States and Solvin in Europe. Asahi Chemical Co. and Kureha Chemical Industries are suppliers of VDC resins in Japan. Additional manufacturers of exclusively VDC latexes include W. R. Grace and Rohm Haas in the United States, and Scott-Bader in Europe. Local suppliers of VDC resins have also been reported in Russia and the People s Republic of China. [Pg.9021]

Despite encapsulation by PVC, compounds such as the above should contain a biocide if used as plastic lumber outdoors. Those reported effective include thiazo-lyl benzimidazole (Irgaguard F3000 Ciba), dichlorooctylisothiazolone (Vinyzene SB27 (Rohm Haas) and Micro-Chek 11 (Ferro), and zinc borate (Borogard ZB US Borax). Wood fiber composites are discussed in greater detail in Chapter 17. [Pg.105]

Historically, the development of the acrylates proceeded slowly they first received serious attention from Otto Rohm. AcryUc acid (propenoic acid) was first prepared by the air oxidation of acrolein in 1843 (1,2). Methyl and ethyl acrylate were prepared in 1873, but were not observed to polymerize at that time (3). In 1880 poly(methyl acrylate) was reported by G. W. A. Kahlbaum, who noted that on dry distillation up to 320°C the polymer did not depolymerize (4). Rohm observed the remarkable properties of acryUc polymers while preparing for his doctoral dissertation in 1901 however, a quarter of a century elapsed before he was able to translate his observations into commercial reaUty. He obtained a U.S. patent on the sulfur vulcanization of acrylates in 1912 (5). Based on the continuing work in Rohm s laboratory, the first limited production of acrylates began in 1927 by the Rohm and Haas Company in Darmstadt, Germany (6). Use of this class of compounds has grown from that time to a total U.S. consumption in 1989 of approximately 400,000 metric tons. Total worldwide consumption is probably twice that. [Pg.162]

The most stable resin for many of our purposes has proven to be a copolymer of ethyl methacrylate and methyl acrylate. This comes as little surprise the Rohm and Haas Company has for years sold a durable resin based on these two monomers, Acryloid B-72 (6,28). We have also prepared polymers of similar physical properties based on methyl methacrylate and ethyl acrylate and have found that their behavior is practically the same - the methyl and ethyl groups apparently do not become seriously involved in crosslinking. As reported elsewhere( 23), rather than crosslink, Acryloid B-72 tends to chain break under visible and near-ultraviolet radiation, although at a very slow rate. Polyvinylacetate is another polymer used in the care of museum objects that tends more to chain break than crosslink under these conditions(23), but it is not our purpose to discuss its properties at this time. [Pg.193]

The first attempts to use macroporous polystyrene supports for onium ion catalysts were reported in the early papers of Brown and Jenkins 54) and of Regen 89).
