1 Experiment 15: Exploring the World of Polymers Objective: In this experiment‚ you will explore a class of chemical compounds known as polymers. You will synthesize and modify polymers‚ test their properties and use a fabrication technique to produce an object from a polymer. Introduction (See Tro‚ pp 985-987.) The importance of both natural and synthetic polymers in our lives cannot be overestimated. The desirable properties of these macromolecules‚ such as tensile strength and flexibility

Chemistry 26/03/2013 The polymer Introduction What is polymer? Polymer is a huge macromolecule comprise many thousands of small molecules created through Joining together chemically. Polymers are everywhere in our life. Many industries extremely rely on polymers‚ for example‚ food court‚ tons o ’toys and dollar dungeon. Those all are stuff made out of polymers. In addition there are lots kind of polymers ‚ such as aramid‚ Carbon fiber‚ Rayon and so on. Now‚ this Essay will investigate Tons

to forming a joint venture in China focused on 3G‚ or more specifically‚ TD-SCDMA (time division-synchronous code division multiple access) and W-CDMA. The joint venture will focus on research and development‚ manufacturing and sales of 3G network systems. The JV will begin offering its first TD-SCDMA and W-CDMA systems next year under China Puritan’s Potevio label. The TD-SCDMA standard is being billed as a Chinese alternative to 3G. In addition to 3G services‚ the venture also will offer

6. POLYMERS and elastomers Lecture no. 1 Objectives: Definition‚ Functionality‚ Classification of high polymers – based on origin‚ molecular structure. 6.1.1. DEFINITION: The word polymer is derived from the two greek words‚ poly and meros‚ meaning many and parts or units respectively. Polymers are macro molecules formed by linking smaller molecules repeatedly‚ called monomers. Examples: Polythene is formed by linking a large number of ethene (or ethylene) molecules together

1. Important characteristics required for materials in Automotive Engineering Polymers have been used in the automotive industry for many decades. It is regarded as an efficient material as it is very durable and could significantly reduce production costs. However‚ as technology advances‚ new polymers are found and better alternatives are paved for the automotive industry. The vehicles we see today are very different than that of the yesteryears. This proves how far the automotive industry has

3.1. IJV local environment This section discusses in detail the effect of national culture and organization culture on the performance of Sino-foreign joint ventures‚ based on previous studies. 3.1.1. National culture Culture is regarded as a “system of shared values and beliefs” (Saloner‚ Shepard and Podolny 2001) that aims to solve problems that arise due to external adaption and internal adaptation of the organizations (Schein 1985). External adaptation is defining the strategy and main objectives
