What is the difference between alkanes and polymers




















They are organic materials similar to most insulating materials. The most important property of these materials is the processability through dispersion. They do not show mechanical properties similar to other polymer materials but are able to offer high electrical conductivity. Moreover, we can fine-tune the electric properties of these materials through methods such as organic synthesis and advanced dispersion techniques.

The major class of conducting polymers include linear backbone polymer blacks and the copolymers of that material. Some examples for some organic conductive polymers include polyfluorenes, polypyrenes, polyazulenes, polyphenylenes, etc. When considering the production of conductive polymer materials, we can prepare them through different methods.

The most common method is the oxidative coupling of monocyclic precursors. The two other methods for this production are chemical synthesis and electro-copolymerization. They have remained unchanged for millions of years; alkenes are less stable than alkanes and more stable than alkynes; alkynes are more reactive than alkanes and alkenes. Alkanes are also called paraffin; alkenes are also called olefin or olefin; alkynes are also called acetylene.

There are two types of common polymers that are basically just alkanes with very long chains: polyethylene and polypropylene.

But there are a large number of other polymers that are made of much more complex parts. The essential differences between a polymer like polypropylene or polyethylene and an alkane are the size of the molecule and the purity of the molecules. Polymers are big, really big, often containing from thousands to hundreds of thousands of carbons. And, they are often made of mixtures rather than a pure alkane of a fixed number of carbons.

These properties arise from the mechanisms of their creation which usually involve long chains of reaction where small molecules monomers such as ethylene or propylene are joined together often via a radical reaction to create long chains.

These reactions can't be controlled precisely enough to give a single product so a mix of products with a distribution of chain lengths and "branchiness" usually results. To some extent the branchiness can be controlled and this yields different grades of polymer some clever catalysts can give much more control of chain length. The properties of polymers differ from those of alkenes mainly because of the size of the molecules.

Though you can get some idea of the types of property to expect by following the properties of progressively larger alkanes. Small alkanes are gases, middle-sized alkanes are volatile liquids, larger alkanes dozens of carbons are often waxy solids.

Polyethylene is just like an extreme version of the waxy solid depending a little on how it is processed. Sign up to join this community. The best answers are voted up and rise to the top.

Nevertheless, synthetic monomers and polymers played a significant role in the history of plastics , revolutionizing material sciences in the early twentieth century and consequently emerging to play a prominent role in the modern industrial economy.

The ability of chemists to engineer synthetic molecules to achieve a desired set of properties such as electrical conductivity, heat resistance, impact resistance , strength, stiffness, and density changed the world. The main difference between monomers and polymers is that the former is the necessary component that forms the latter.

Polymers are comprised of a chain of monomers through a process known as polymerization.
