Special grades of glycidyl ether epoxies have been made with components such as glycerol, polyglycols, pentaerythritol, and cashew nut oil. Other epoxy-polyglycidol resins have been produced from the reaction of epichlorohydrin and polyester polyol based on...

Commercial products are available where n varies from 2 to 7. The flexible epoxy resins based on polyglycol also make excellent reactive diluents because they have a viscosity of 100 cP at 25°C. Table 4.4 shows the effect of two polyglycol diepoxides on the physical properties of a cured epoxy system. Another type of flexible epoxy resin is derived from dimerized unsaturated fatty acid, cashew nut oils, and other vegetable oils. Other flexible epoxy resins can be made with thiols, aliphatic acids, and hydroxyl-terminated compounds. Applications where flexible epoxy resins are valued include... 

Cashew (Anacardium occidentale). Toschi et al. (91) have given details of the fatty acids, triacylglycerols, sterols, and tocopherols in cashew nut oil. The major fatty acids are palmitic (9-14%), stearic (6-12%), oleic (57-65%), and linoleic (16-18%), and the major triacylglycerols are OOO, POO, OOSt, OOL, and POL. 

The cashew (Anacardium occidentale L.) is an evergreen species native to tropical America and contains 47% oil (w/w) (1, 68). Other components of cashew nuts include carbohydrate (27.1%), protein (18.2%), water (5.2%), and ash (2.5%) The predominant fatty acid in cashew nut oil is oleic acid (57.3-65.1%), followed by linoleic (15.6-18.6%), and palmitic (9.0-14.2%) acids (Table 10) (68). Cashew nut oil contains 1.4% unsaponifiable matter (w/w), of which 76.2-82.7% is p-sitosterol. Other sterols present in cashew nut oil include A -avenasterol, campesterol, fucosterol, cholesterol, and stigmasterol (68). Cashew nut oil contains 45.3-83.5 mg/lOOg y-tocopherol other tocopherols present are a-tocopherol (2.8-8.2 mg/lOOg) and 5-tocopherol (2.0-5.9 mg/100 g) (68).

Other epoxy resins are also being manufactured, but their commercial j utilization is not so far advanced as those based on bisphenol A and i epichlorohydrin. For instance, resorcinol and a mixture of diphenol-poly-(hydroxyphenyl)-pentadecanes, obtained by the addition reaction of phenol with an unsaturated phenol derived from cashew-nut oil (see structure below) can be reacted with epichlorohydrin to produce epoxy resins. ...

There is a wide variety of chemicals that can be used to modify specific properties of the resin, such as resistance to mechanical or thermal shock, increase elongation, and higher impact strength and flexibility. Usually this will involve a trade-off of some other property, such as physical strength, electrical properties, resistance to chemicals or solvents, and/or performance at elevated temperatures. For epoxies, there are DER-type flexible resins and monofunctional epoxide compounds, such as epoxidized cashew nut oil flexibilizer. Typically 30% or less by weight of these can be used, they can also be used at ratios of 1 1 to obtain a flexible and rubbery cured composition. The additives are also shelf-stable when blended with the resin. 

Meanwhile, also phenol-substituted Upids are the focus of catalytic transformations within the framework of sustainable chemistry. Typical examples are anacardic acid, cardol, 2-methylcardol, and the industrially most important compound cardanol (Figure 6.12). These phenols have preferentially Cjg side chains with a varying number of double bonds [17]. The compounds are manufactured from cashew nut oil (cashew nut shell liquid or CNSL). Currently, an annual production of450 0001 is estimated, which is continuously increasing.
