Alkenylsuccinic anhydrides made from several linear alpha olefins are used in paper sizing, detergents, and other uses. Sulfosuccinic acid esters serve as surface active agents. Alkyd resins (qv) are used as surface coatings. Chlorendric anhydride [115-27-5] is used as a flame resistant component (see Flame retardants). Tetrahydrophthalic acid [88-98-2] and hexahydrophthalic anhydride [85-42-7] have specialty resin appHcations. Gas barrier films made by grafting maleic anhydride to polypropylene [25085-53-4] film are used in food packaging (qv). Poly(maleic anhydride) [24937-72-2] is used as a scale preventer and corrosion inhibitor (see Corrosion and corrosion control). Maleic anhydride forms copolymers with ethylene glycol methyl vinyl ethers which are partially esterified for biomedical and pharmaceutical uses (189) (see Pharmaceuticals). [Pg.461]

Resing and Moniz 60) cured DGEBA with three different curing agents, piperidine, hexahydrophthalic anhydride (HHPA) and nadic methyl anhydride (NMA). Spectra were collected with C-13 NMR using cross polarization and high power decoupling. [Pg.100]

Garroway, Ritchie, and Moniz 70 continued the characterization of epoxy polymers with respect to molecular motion using variable temperature, solid state C-13 NMR. DGEBA was the epoxy of interest. The DGEBA was cured with piperidine, m-phenylene diamine, hexahydrophthalic anhydride and nadic methyl anhydride. The piperidine cured DGEBA had the best resolved polymer spectra.

Antoon and Koenig 67) found a first-order dependence with respect to the tertiary amine, but they were not able to distinguish between zero-, first-, and second-order kinetics with respect to monomers. Approximately the same fit was obtained for all mentioned orders below the gel point. Peyser and Bascom reported first-order kinetics for the curing of the diglycidyl ether of bisphenol A with hexahydrophthalic anhydride 94) and second-order kinetics with respect to the same epoxide cured with nadic methyl anhydride 93). They also pointed out the uncertainty in determining the reaction order. [Pg.126]

After the primary amines, acid anhydrides are the next most important class of epoxy curing agents, although these are not used as often in adhesive systems as they are in casting compounds, encapsulants, molding compounds, etc. The most common types of anhydrides are hexahydrophthalic anhydride (HHPA), phthalic anhydride (PA), nadic methyl anhydride (NMA), and pyromellitic dianhydride (PMDA), although there are several others. Chemical structures of several anhydrides are illustrated in Fig. 5.6. [Pg.99]

Phthalic anhydride is the cheapest anhydride curing agent, but it has the disadvantage of being rather difhcult to mix with the resin. Liquid anhydrides (e.g., dodecenylsuccinic anhydride and nadic methyl anhydride), low-melting anhydrides (e.g., hexahydrophthalic anhydride), and eutectic mixtures are more easily incorporated into the resin. Since maleic anhydride produces brittle products, it is seldom used by itself and is used as a secondary hardener in admixture with other anhydrides. Dodecenylsuccinic anhydride imparts flexibility into the casting, whereas chlorendic anhydride confers flame resistance. [Pg.502]

Cyclic acid anhydrides are widely employed as curing agents for epoxy resins. Both mono- and dianhydrides are used. Examples of anhydrides which find application are maleic anhydride (MA) (XIX), dodecenylsuccinic anhydride (DDSA) (XX), hexahydrophthalic anhydride (HPA) (XXI), phthalic anhydride (PA) (30(11), pyromellitic dianhydride MDA) (XXIII), nadic methyl anhydride (NMA) (a mixture of maleic anhydride adducts of methylcyclopentadienes cf.. Section 10.2.2.3) (XXIV) and chlorendic (HET) anhydride (XXV see also Section 102.2.3). [Pg.381]

It is possible that the above scheme does not always apply. For example, when a low molecular weight bisphenol A-epichlorhydrin resin was cured with hexahydrophthalic anhydride or nadic methyl anhydride there was no indication of ether formation during the reaction prior to the gel point. It has been suggested, on the basis of kinetic data, that these cases involve a termolecular transition state which results in the production of a diester [8] ... [Pg.383]

Anhydrides are also high temperature curing agents. The reaction with epoxy resins is slow in the absence of an accelerator, and requires quite large quantities. Typical substances used include methyl nadic anhydride and hexahydrophthalic anhydride. (Methyl nadic anhydride is a convenient liquid at room temperature, whereas nadic anhydride is a solid.)... [Pg.204]
