Importing in Foreign Markets and Market Position Read Closing Case: Embraer and Brazilian Importing at the end of Chapter 16 and write a three- to four-page paper, excluding the title and reference pages, with a detailed analysis that answers the following: • Examine the main benefits of importing products to be used in products of other goods. Present examples of the benefits. • Explain the sustainability of a company like Embraer if it neither exported nor imported products. • Examine the benefits and concerns that can occur when countries use protectionist policies in trade. • Examine whether Embraer should have more of the over 300,000 parts for its planes produced by Brazilian Manufacturers or should the company continue to pursue outsourcing. Keep in mind the need to establish as many competitive advantages as possible. • Analyze the impact that government subsidies could have on Embraer’s international competitive ability.
carboxylic moiety and the carbonyl oxygen of the ester group in the polymer molecules. This bonding increase degree of compactness of the polymer and decrease its porosity and permeability , minimizing release of an encapsulating agent. When the pH of aqueous medium is increased, Eudragit S100 start to dissolve as carboxylic functional groups ionizes. The reported theoretical dissolution threshold is pH 7.0 and pKa of polymer molecules is believed to be approximately 6 . Moreover, swelling of Eudragit S100 matrix may accompany the dissolution process contributing to release. It is believed that Eudragit S swells at pH above 6.5 . Therefore, release of active substance may be due to the combination of swelling and dissolution. Hydroxyl propyl methyl cellulose phthalate (HPMCP): These are natural cellulose synthetically modified to produce partly methyl ethers, 2-hydroxy propyl ethers and phthalyl esters. HPMCP is manufactured by esterification of hypromellose with phthalic anhydride. The level of alkyloxy and carboxybenzoyl substitutions determines the properties of polymer and in particular the pH at which it dissolves in aqueous medium. HPMCP (also known as Hypromellose phthalate)  is commonly used in oral pharmaceutical formulations as an enteric coating material for tablets or granules [134-138]. Hypromellose phthalate is insoluble in gastric fluid, but will swell and dissolve speedily in the upper intestine. These polymers can be used as coating agents because they do not necessitate the addition of plasticizer or other film formers to fabricate coatings for oral formulations . Hydroxypropyl methylcellulose phthalate (HPMCP), available in the market since 1971, it is a monophthalic acid ester of hypromellose, containing methoxy (-OCH3), 2-hydroxypropoxy (- OCH 2CHOHCH3) and phthaloyl (o-carboxybenzoyl C8H5O3) groups so, HPMCP is a cellulose in which some of the hydroxyl groups are replaced with methyl ethers, 2-hydroxy propyl ethers, or phthalyl esters. Numerous different types of hypromellose phthalate are commercially presented with molecular weights in the range 20 000–200 000. Typical average values are 80000–130000 . These types are (HP50, HP55 and HP55S) where HP55 grade is usually used for enteric coating, HP55S grade, because of its higher degree of polymerization compared with HP-55, it have greater solution viscosity, greater mechanical strength of the film and HP-50 dissolves at a lower pH value and is therefore appropriate for preparations which are designed to disintegrate in the upper part of the small intestine.>GET ANSWER
