Class 12 CHEMISTRY What are polymers ? What are polymers ? Video SolutionText SolutionVerified by Experts Polymers are high molecular mass substances (103−107)u) consisting of a very large number of simple repeating structure units joined together through covalent bonds in a linear fashion. They...
What are polymers? For one thing, they are complex and giant molecules and are different from low molecular weight compounds like, say, common salt. To contrast the difference, the molecular weight of common salt is only 58.5, while that of a polymer can be as high as several hundred thous...
Just wondering, if melamine and polymers are used to make plastic dishes and storage containers for food...when people put them in the micro-wave and get all of those electrons hopping around...do the organic elements of the melamine and polymers bond with the organic properties in the food...
Polymers:Polymers occur naturally and they can also be synthesized. Natural polymers include starch, cellulose, DNA, proteins and many more. Synthetic polymers include nylon, polyethylene and teflon to name a few.Answer and Explanation: The word "polymer" comes from two Greek words: poly which ...
Polymerchemistry is the other area in which polyols are often used. The multiple hydroxyl groups contained in the compound are used for organic reactions — most often as reactants for the purpose of creating polymers. These polymers are then used to create items like shoe soles, Spandex fabric...
