Structure and uses of nylon

Extracts from this document...

Introduction

Nylon--Milestone of Polymer chemistry Nylon is a family of synthetic polymers known as polyamides. Nylon was first produced on February 28, 1935, by Wallace Carothers at DuPont Experimental Station. Nylon is one of the most commonly used polymers. Nylon comes in many types, the two most common for textile and plastics industries are: Nylon 6 and Nylon 6, 6. Nylon 6 Nylon 6, 6 The characteristic features of nylon 6, 6 include: * Pleats and creases can be created through heating the nylon, when they cool the creases stay. * It has a more compact molecular structure compare to Nylon 6 * It has a better weathering properties and better sunlight resistance * It felt soft to the touch * Higher melting point (256 �C / 492.8 �F) ...read more.

Middle

Nylon is malleable, and is commonly used for shock jobs since it stretches when force is exerted suddenly. This makes it advantageous since the stretching does not interfere with durability. Nylon is popular applied for industrial use since it has great shock absorption and is unaffected by changes in temperature, also it is elastic and has great abrasion resistance. However, high stretching may cause internal abrasion, leading to tear. 3. Impervious to sunlight Nylon is unaffected by sunlight, which make it preferable than ropes made from fiber. Nylon will withstand sunlight damage for short period of time. It also can withstand destruction from chemicals over short time. 4. Resistant to water Nylon is suited for temporary mooring and towing because it is impervious to water, alkalis, dilute acids and petroleum products, etc. ...read more.

Conclusion

Electrostatic discharge is caused by fraction. When people touch a product of Nylon, it is easy to get shock by Electrostatic discharge. Nylon is flammable, when a product of Nylon gets fire, it will burn very fast. Summary: Nylon is easy to make, it has many good physical and chemical properties. When the Nylon formed, the reaction won't have many waste products. In conclusion, those things make nylon be a very useful and beneficial chemical in our society. Source citation 1.

    This is the reason why calcium chloride is capable to conduct electricity when is dissolved but incapable when is solid. In the case of covalent bonds we observe that they are poor conductors as solid and liquid because all electrons are tied up in covalent bonds, this explains the conductivity of iodine.

    This happens in three steps: the initiation, propagation and termination. The initiation stage happens when the initiator molecule (in this case the tetrafluroethylene molecule) breaks apart, to leave two unbonded electrons free. These molecules are also known as free radicals, and are highly reactive.
