Polymers are the archetypal modern materials, used in every aspect of everyday life. This Primer gives a thorough introduction to Polymer Chemistry, ranging from a historical perspective, through the development of high-tonnage materials earlier in the twentieth century, to modern high-performance ...

The word “polymer” – derives from the Greek word“polumeros”and that means “many parts” – is used to describe a long chain molecule made up of numerous repeating units called monomers. Either natural (organic) or synthetic (man-made), polymers are ubiquitous in everyday life. They a...

内容提示: Polymers in everyday things – contact lenses(Background information)Polymers are a part of everyday life and examples can be found almost anywhere. Many peoplethink of polymers simply as plastics used for packaging, in household objects and for makingfibres, but this is just the tip...
Polymers can be naturally found in plants and animals (natural polymers) or can be human-made (synthetic polymers). Different polymers have a number of unique physical and chemical properties, due to which they find usage in everyday life. ...
1. T_g ,the glass transition temperature, is the temperature below which polymers become (choose correct answe) (a) rubbery (b) Glassy/Brittle 2. Explain why should a polymer used for an ice cube tray be above its T_g in use.
The chemical structures of the polymers mentioned in the text Full size image The degradation process of rubber Rubber is a natural polymer and was one of the earliest polymers employed by mankind. It is extensively used in the production of several goods, including mattresses, tyres, gloves, an...
Dextran, another type of carbohydrate polymer, is popular in many drug delivery systems, where it is often used in the delivery of drugs that are unstable or do not pass through cellular membranes easily. Alginates are carbohydrate polymers that are often used are microspheres, gels, and nanopar...
