Synthetic rubber

increased rubber consumption for vehicle tires. More plantations were established to supply demand, increasing deforestation. Tucker explains this when he writes “In order to create the plantations, they clear-cut the forest, burning the biomass or in some cases organizing salvage logging of valuable hardwood trees” (Pg 148). Even though rubber consumption increased dramatically over the decades, its consequences were not as significant as they could have been because synthetic rubber derived…

The Astroturf was the first synthetic turf created in 1965. This turf reduced the amount of maintenance, but resembled more of a carpet. Field Turf is the most recent type of turf which is mixed with rubber and sand. (Livesay,Reda, & Nauman 2006) Although the turf has advanced greatly compared the original synthetic fields. Field turf increases speed, acceleration and torque while playing, which untimely leads to more injuries…

Slate roofing is an excellent choice for many home and business owners, but the material is not without its pitfalls. Though attractive and durable, roofing slate is also heavy and difficult to transport and install. Here is what you need to know about slate before choosing it for your roof. Slate Pros Slate lasts a long time and • Lifespan - One of the most compelling reasons to choose slate roofing tiles is longevity. Slate roofs last 100 to 150 years, easily surpassing the typical 30-year…

latex itself. There are three types of latex allergies – two of which are non-life-threatening, and one that is. Definition and Facts Natural latex, usually referred to as rubber latex, is a tree-derived, natural rubber substance from the hevea brasiliensis from the Eurphorbiaceae family. Natural latex differs from synthetic latex, as artificial latex does not exhibit the reaction that natural latex does; however, both are referred to synonymously as "latex." Incidents of latex allergies span…

It sparked his interest in theoretical and experimental chemistry. Shortly after February 6th 1928, Carothers began studying structure and synthesis of polymers. His boss at the time asked him to research acetylene polymers that might lead to synthetic rubber. He began reacting dibasic acids with diols, today known as esterfication. The result was long chains of molecules called polyesters. After many trials Carothers discovered and concluded that the water product was limiting the length of…

This birthed synthetics. The two most prominent are oil, and rubber. These are items that have a very large impact on the way we live today. “While synthetic oil was created by the German scientists in order to account for the extreme shortage of its natural counterpart, synthetic rubber was invented in the US shortly after by the American scientist Waldo Semon. It is necessary to mention that the polyethylene…

including motor vehicles, watercraft, train locomotives and aircraft. They are usually a legal requirement for most of these crafts. A wiper usually consists of metal arm balanced at one end and a long rubber blade attached to the other end. The metal arm is mostly powered by electric motor. The rubber blade is swung over the glass, back and forth. This action pushes water, snow and other matter causing poor visibility. The speed is usually adjustable. Blade wipers also have other applications.…

Synthetic reeds are much easier to play on than cane reeds. Synthetic reeds are plastic, so they provide less resistance than cane reeds. “Synthetic reeds do not have the same feel as traditional cane when played and the tone is quite different. For this reason, most saxophonists choose to play traditional cane reeds.” (Tracy…

between the double bond of the dienophiles and the carbon atoms of the one and four positions in the diene. In the 1890’s, Alder began to study the general experimental properties of the diene synthesis and the overall concept of the method for synthetic purposes. Kurt Alder was an able stereo chemist and showed how a diene addition took place at double bounds with a cis configuration. Alder showed that the reaction was equally general with respect to the dienophiles, given that the double bond…
