Definition and Characteristics
Rubber-like polymers, also known as elastomers, exhibit a few standout characteristics that set them apart. At their core, they are long-chain molecules that possess a unique arrangement, enabling them to stretch and return to their original form, akin to a rubber band. However, not all polymers have this elastic quality. The key characteristics of rubber-like polymers include:
- Elasticity: This allows materials to deform under stress and recover their shape once the stress is removed.
- Viscoelasticity: A mix of viscous and elastic behavior means they can absorb energy and dissipate it slowly over time.
- Low glass transition temperature: This implies that they remain flexible at lower temperatures, facilitating extensive applications.
In practical terms, these properties lead to both advantageous and sometimes, limiting factors when considering their uses. For instance, while their elastic nature can be beneficial for shock absorption, it can also make them prone to fatigue over long periods.
Historical Development
The journey of rubber-like polymers is anything but linear. Historically, these materials have undergone significant transformations, with roots stretching back to natural rubber derived from the sap of rubber trees, notably Hevea brasiliensis. The early use of natural rubber, which dates back centuries, laid the groundwork for understanding its potential in various applications.
In the 19th century, the introduction of vulcanization by Charles Goodyear revolutionized rubber technology by enhancing its strength and elasticity. This technique essentially connected the polymer chains by means of sulfur crosslinks, which increased resilience dramatically. Such progress marked a turning point, leading onto innovations in synthetic rubber during World War II when natural rubber became scarce. Companies like Goodyear and Firestone began producing synthetic alternatives, paving the way for contemporary advancements.
