Polyamides are formed by step growth reaction of aliphatic diamines with diacid. a. Suppose for a reaction, the initial concentration of aliphatic diamine and diacid were 2 moles and 6 moles, respectively. After 2 hours, the reaction has been stopped. What will be the degree of polymerization for 95% extent of reaction. b. Now suppose the initial moles of aliphatic diamines are doubled. How will it impact the degree of polymerization? c. Graphically explain the impact of initial mole ratio on the weight fraction distribution and degree of polymerization in linear step growth reaction, given that extent of polymerization is 99%.
A company is not just made up of numbers, results and productivity. The moral and ethical values and the internal and external posture of a company, the so-called organizational culture, can make all the difference in business success (Carvalho, 2010). In this context, Natura is an example of a successful business culture focused on “well-being”. It is the largest multinational Brazilian cosmetic and beauty products, and also present in Argentina, Chile, Colombia, France, Mexico, Peru, and United States. The company was founded in 1969 by Luiz Seabra, but it was only after a year that he opened his first store, where he himself served the customers. After a few years direct sale was adopted as their main business model and the store was closed. In this business model, without any physical store, anyone could be one of their “beauty consultants”, who were in charge of the direct sales, which led the brand to expand rapidly across the country. “In the Brazilian market, they are the leading direct selling player with more than 1.8 million Natura consultants, and they are currently expanding their retail sector through own stores and partnerships with drugstores chains” (Certified B Corporation). Recently, Natura, Aesop and The Body Shop came together and gave rise to the Natura & Co group. In order to gather information and diagnose Natura’s organizational culture, I used five main sources. The first one was Natura’s website, used to assess the way it introduces itself to the public and the way it communicates with consumers. On the website it is also possible to look at the products they offer, the history of the brand, and the social and environmental causes they are involved with. In addition, I found it relevant to start researching there, because through it we can analyze Natura’s perspective on itself, which influences its organizational culture. The second source I based my research on was Natura’s Annual Report of 2017. In this document it is possible to analyze the brand positioning, as well as its mission and values. Moreover, the annual report provides information on the company management, staff training, strategies to reduce environmental impacts, and the most significant activities of the year w>GET ANSWER
