Polymer chemistry paint

NOTE The same polymer chemistries employed in the BW deposit control treatment market sector are also made available to other markets such as waste water, cooling water, potable water production from brackish or saline supplies, metal finishing, paint and coatings, electronics, pulp and paper, and more. 

The commercial process for the production of vinyl acetate monomer (VAM) has evolved over the years. In the 1930s, Wacker developed a process based upon the gas-phase conversion of acetylene and acetic acid over a zinc acetate carbon-supported catalyst. This chemistry and process eventually gave way in the late 1960s to a more economically favorable gas-phase conversion of ethylene and acetic acid over a palladium-based silica-supported catalyst. Today, most of the world s vinyl acetate is derived from the ethylene-based process. The end uses of vinyl acetate are diverse and range from die protective laminate film used in automotive safety glass to polymer-based paints and adhesives. 

The ACS High Polymer Forum, similar to today s Macromolecular Secretariat, with the help of C.S. Fuller and A.C. Elm, began meeting at the 19 16 Atlantic City ACS meeting. Through the efforts of the Polymer Forum, the Division of Paint, Varnish and Plastics Chemistry and others in 1948 a group of university and industry chemists petitioned the American Chemical Society to establish a separate division of Polymer Chemistry. After a probation period...

In addition to exploiting the potential of polymer chemistry, Du Pont continued to commercialize new products in the divisions that had created their integrated learning bases before World War II. It did so in chemicals, including ammonia and methyl, and also in paints, finishes, and nonporous fabrics. After World War II, Du Pont began to build on its earlier potential in the production of insecticides and other agricultural chemicals (SIC 2879). Its innovative selective-weed-control products enabled it to capture 20 percent of the U.S. herbicide market by 1960. ... 

The extension of these principles to molecules and macromolecules based on renewable resources has been applied to polymer chemistry and technology, mostly in two areas requiring viscous materials, namely (i) the preparation of liquid polyols to be used in the manufacture of polyurethanes, and (ii) the synthesis of macromol-ecular rheology modifiers. A typical polyol for the synthesis of polyurethane foams is obtained industrially from the oxypropylation of sorbitol, [3] whereas hydroxypropyl cellulose represents a major commodity for the rheological control of paints, foodstuff, cosmetics, etc. [4].

Less than 50 years ago, virtually all paint and other surface coating formulations were based on hydrocarbon solvents as the liquid phase. Following advances made in emulsion or latex polymer chemistry, resin systems became available which had the necessary properties of mechanical strength, durability and cost effectiveness such that today, emulsion paint dominates the decorative coatings area. This trend was assisted by the introduction of legislation which discouraged and, in some cases, prohibited the use of formulations which resulted in VOC (volatile organic carbon) emission to atmosphere. 

Interest in the field of polymer chemistry became so intense that a High Polymer Forimi, similar to our present symposium system, was established. The wide range of interest in the polymer field was evidenced by the several divisions sponsoring the Forum Paint, Varnish and Plastics Physical, Inorganic Rubber Chemistry Cellulose Colloid Organic and Petroleum. From 19 6 to 19 9 1 2 papers were presented at 27 sessions of The High Polymer Forum.

The unique surface characteristics of polysiloxanes mean that they are extensively used as surfactants. Silicone surfactants have been thoroughly studied and described in numerous articles. For an extensive, in-depth discussion of this subject, a recent chapter by Hill,476 and his introductory chapter in the monograph he later edited,477 are excellent references. In the latter monograph, many aspects of silicone surfactants are described in 12 chapters. In the introduction, Hill discusses the chemistry of silicone surfactants, surface activity, aggregation behavior of silicone surfactants in various media, and their key applications in polyurethane foam manufacture, in textile and fiber industry, in personal care, and in paint and coating industries. All this information (with 200 cited references) provides a broad background for the discussion of more specific issues covered in other chapters. Thus, surfactants based on silicone polyether co-polymers are surveyed.478 Novel siloxane surfactant structures,479 surface activity and aggregation phenomena,480 silicone surfactants application in the formation of polyurethane foam,481 foam control and...
