Polymers, Resins, and Coatings. Peroxyesters of neodecanoic acid, such as / i -butylperoxyneodecanoate [26748-41-4] and a-cumyl peroxyneodecanoate [26748-47-0], constitute one of the most important uses for neodecanoic acid. These materials are used as free-radical initiators in the polymeri2ation of vinyl chloride (85), acrylates (86), ethylene (87), styrene [100-42-5] (87), and in the copolymeri2ation of vinyl chloride with other monomers, such as propylene [115-07-1] (88), or acrylates (89). The peroxyesters are also used as curing agents for resins (90). 

The formaldehyde process is an air oxidation of methanol, CH3OH, which has water as a by-product. Formaldehyde is a gas at room temperature, but is usually handled either as a water solution called formalin or as polymers called paraformaldehyde and trioxane. Both are readily converted back ro formaldehyde. Some uses of formaldehyde are the manufacture of polymer resins and as a germicide.

BCME was used in the past to make several types of polymers, resins and textiles. However, because BCME is believed to cause cancer in humans, these uses have been stopped. BCME is now used only in small amounts inside fully enclosed systems in chemical plants. More information on the properties and uses of BCME is presented in Chapters 3 and 4.

Polymer resins and their major possible products are collected in Table 1.2. A high purity of the feedstock is the best guarantee of clean and possibly marketable products. Generally, the value of the products obtained is insufficient to warrant the process. However, recently the concept of feedstock recycling created a political current that is more favourable to pyrolysis than the corresponding economic context.

Primary ureas 1365 are good substrates in rhodium-catalyzed N-H insertion reactions with an array of 2-diazo-l,3-keto esters 1364. The products from the insertion reaction cyclize with the aid of acid to yield imidazolones 1366. This chemistry has been translated onto insoluble polymer resins and utilized to prepare a small array of imidazolones (Scheme 351) <20030L511, 2004JOC8829>. 

The deposited-film technique is particularly useful for polymers, resins, and amorphous solids. The samples are dissolved in a reasonably volatile solvent, the solution poured onto a suitable window, and the solvent evaporated by gentle heating or vacuum treatment. 

Irganox MD 1024 is approved by the FDA for use in packaging polymers, resins and adhesives intended for food contact applications. It is approved in many countries for food contact applications. 

During the industry s restructuring in the early 1980s, Exxon Chemical sold off most of its specialty petrochemical units to Du Pont and other chemical companies, and concentrated its R D on intermediates and polymers. In the early 1990s product development was accomplished through joint ventures, such as one begun in 1990 with Monsanto to improve thermoplastic elastomers, another in 1992 with Mitsui Petrochemicals for the next generation of ethylene polymer resins, and a third in 1994 with Hoechst to refine... 

Manufacturer sales in the U.S. adhesives industry are rapidly approaching 2 billion dollars per year. The industry already consumes more polymers than the industiral coating industry - 1,350 million pounds compared to 1,250 million pounds in 1978. About 1.4 billion pounds of film forming polymers, resin and additives were used by the adhesives industry in 1979 ... 

Polyolefins and Polyamides, Modern hot-melt adhesive compounds are commonly based on polymers of the polyolefin or polyamide type. The polyolefin-based ones are usually modified with other natural and synthetic polymer resins and waxes. The melt temperatures of hot melts vary rather widely. Some begin to melt just above 100°C, whereas others may require temperatures in the range of 200°C to melt. The high-temperature ones might very well damage the artifacts being bonded. Hot melts may be of considerable interest in conservation gluing, but additional research is needed on the most appropriate formulations and forms of application.

Since very recently the number of papers on microwave-assisted polymerization reactions has been growing almost exponentially [3], the purpose of this chapter is to provide useful details about the application of microwave irradiation to polymer chemistry during the last few years. A survey of past achievements in polymer synthesis and polymer composites can be found in review papers [1-8] whereas fundamentals of electromagnetic heating and processing of polymers, resins and related composites have been summarized by Parodi [9]. 

This suspension system can be used with dispersion containing a maximum solid content of 55% by weight of polymer resin and colloidal silica or polymer resin, colloidal silica and carbonaceous material such as pitch. The minimum solid content is only limited by the amount of water that is practical to add to the sand mix to obtain practical cores.

Industrially applied polymerizable formulations are composed of mixtures of mono- and multifunctional monomers and oligomers (see Table 11.1) containing a photoinitiator and, if required, also additives such as polymers (pre-polymers, resins) and pigments. Table 11.2 presents, as a typical example, the composition of a formulation applied for microfabrication (see Section 11.4). 

In the materials science area, dendrimers have been used for adhesive tie coats to glass, metal, carbon, or polymer surfaces, additives for polymer resins and composites, printing inks, surfactants, cross-linking agents, electrically conductive nano devices,flow regulators, processing aids, and chemical... 

In practice, the terms plastics , polymer , resin and matrix mean very similar things and are used almost interchangeably in reinforced plastics circles without much confusion, although there are minor differences of interest mainly to the specialist.
