Chapter 9 The World of Plastics and Polymers Overview • Plastics are all around us – Polymers‚ materials whose molecules consist of long chain of atoms • Natural • Synthetic • Use of material and impact on economy‚ lifestyle‚ and leisure – Word plastic to some carry connotation “cheap” or “tacky” – Synthetic polymers revolutionised modern life • eg plastics become important in automobile industry‚ some new plastics stronger than steel and resist corrosion‚ less dense than structural

1. What does it mean when a polymer is crosslinked? Crosslinked is one manner in which monomers link together. In this method‚ separate polymer chains are connected via bonds between the individual polymer chains. 2. We discussed how polymer linking and structure contribute to its properties. How would you expect the density‚ elasticity‚ and rigidity of a polymer that is branched to compare to one that is linear? I would expect the density of the linear polymer to be much higher than the density

Polymers in Dentistry A polymer is a very long molecule that is made by linking together many smaller molecules called monomers. Some polymers contain only one type of monomer and others can be made from a combination of two or more different monomers. Polymers can be synthetic (produced by humans) or natural. Polymers that can be heated and molded into specific shapes and forms are commonly known as plastics. All plastics are synthetic polymers. Adhesives‚ chewing gum‚ and polystyrene are also

Polymer Chemistry Classification of Polymers – Notes prepared by The most common way of classifying polymers is to separate them into three groups - thermoplastics‚ thermosets‚ and elastomers5. The thermoplastics can be divided into two types - those that are crystalline and those that are amorphous. You may click on the words in the diagram below to learn more about these classifications. Thermoplastics Molecules in a thermoplastic are held together by relatively weak intermolecular

1.1 DEFINING POLYMERS Polymers are materials of very high molecular weight that are found to have multifarious applications in our modern society. They usually consist of several structural units bound together by covalent bonds [1‚2]. For example‚ polyethylene is a long-chain polymer and is represented by ÀCH2 CH2 CH2 À or ½ÀCH2 CH2 Àn ð1:1:1Þ where the structural (or repeat) unit is ÀCH2ÀCH2À and n represents the chain length of the polymer. Polymers are obtained through

International joint ventures (IJVs)‚ the second type of equity based cross-border alliance‚ have experienced tremendous growth during the last two decades as well. They will continue to represent a major means of global expansion for MNEs. In emerging economies such as China they represent the dominating operation mode for MNEs’ market entry. According to a well-known definition by Shenkar and Zeira an IJV

In Element 3‚ present an example of a company with a wholly-owned subsidiary and a joint venture in two different foreign markets. Explain why the management team of this corporation chose each of the investment models. According to Ball et al.
