Rubber is a polymer, which is a large molecule composed of repeating structural units. It is a natural substance that is harvested from the rubber tree, Hevea brasiliensis, as latex. Synthetic rubber is also produced through the polymerization of monomers.
Structure of Rubber
The basic structure of rubber is a long chain of carbonatoms, with two hydrogenatoms attached to each carbon. This is known as a polyisoprene chain. The double bonds in the polyisoprene chain give rubber its elasticity.
Properties of Rubber
Elasticity: Rubber is known for its high elasticity, allowing it to return to its original shape after being stretched or compressed.
When studying the topic of rubber, consider the following key points:
Understand the structure of rubber at the molecular level, including the arrangement of carbon and hydrogenatoms in the polyisoprene chain.
Learn about the properties of rubber, such as elasticity, insulation, waterproofing, and resilience, and how these properties make it suitable for various applications.
Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
