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...

Polymers: Polyvinyl Acetate and Polymer Ball

Investigating the effectivness of PVA and PVAc as base polymers In the production of a polymer ball. Introduction A monomer refers to a specific group of atoms that from a molecular unit. When monomers are strung together like a long chain they form polymers. A good analogy of polymers, would be long connections of chains which become tangled like a bunch of spaghetti in a pot. The reason for experimenting with, and understanding polymers is because they play such a major roll and are found...

Determination of Unknown Polymer Properties

performed by Ryan Nelson, Peter Glascor, Eric Flowr was to determine the identity of the unknown polymer by comparing its properties to properties of other known polymers. Most likely, the part is one of the five following polymers: polyethylene, polypropylene, polystyrene, polycarbonate, poly(vinyl chloride). These are all extremely common, and have widespread applications in industry. Each of these polymers exhibits properties which allow it to be of unique technological importance. Theoretical...

Polymers in Everyday Life

Polymers are a part of our every day life and without them around, this world would be very, very different, if not impossible to live in. However, most people do not even know what a polymer is, or just how widespread they are around us. Polymers are formed from hydrocarbons, hydrocarbon derivatives, or sometimes from silicon. They are the basis not only for numerous natural materials, but also for most of the synthetic plastics that one encounters in their lives. Polymers consist of extremely large...

Polymer Chains

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 Have Different Structures. They Also Have Different Functions. Describe How the Structures of Different Polymers Relate to Their Function?

Polymers have different structures. They also have different functions. Describe how the structures of different polymers relate to their function? Polymers a large molecules made up of a chain of smaller molecules, known as monomers. The monomers that a polymer is made up of decide its structure and therefore it's function. These monomers are linked and coiled in a very specific manor giving the polymer a specific tertiary structure (an extensively coiled and linked polymer chain caused as a...

Worldwide Medical Polymer Market to 2020 – Industry Survey, Market Size, Competitive Trends: Grand View Research, inc

The global market for medical polymers is expected to reach USD 17.05 billion by 2020, according to a new study by Grand View Research, Inc. Increasing substitution of conventional materials such as glass and metals in medical devices by high performance polymers such as PVC and polypropylene coupled with growing demand for medical devices from the fast developing Asian healthcare market is expected to drive medical polymer demand over the next six years. In addition, growing geriatric population...
