Rubber
Question 1: What is Rubber?
Answer:
Rubber is a natural polymer that can stretch and shrink. It’s an elastomer that, after being deformed, may revert to its previous shape. Rubber is made by the polymerisation of Isoprene (2 methyl-1,3-butadiene.
Question 2: What is the vulcanization of the rubber?
Answer:
Vulcanization is a process of hardening rubbers. The term “Vulcanization” originally comes solely from the reaction of natural rubber with sulfur, which is the most common practice. It has also grown to include the hardening of other (synthetic) rubbers via various means. For example Silicone Rubber and chloroprene rubber (neoprene), etc.
Question 3: Dicarboxylic acids react with diols to form which type of copolymer?
Answer:
Dicarboxylic acids react with diols to form the alternating type of co-polymer type of copolymer. Polyesters obtained by them are glyptal, daozon, etc.
Question 4: What are Rubber products?
Answer:
Commonly used rubber products are mattresses, shoe soles, hot water bottles, balloons, rubber boots, etc.
Question 5: What is the difference between natural and synthetic rubber?
Answer:
Natural rubber is defined as the type of rubber that are produced naturally from the rubber plant Hevea brasiliensis. However, the Synthetic rubber is defined as the type of rubber which is artificially produced from a variety of polymers which provides the rubber its properties.
Question 6: Why are rubbers called elastomers?
Answer:
An elastomer is a type of polymer that exhibits elasticity. Natural rubber is an elastomer manufactured from latex, the milky sap of the rubber tree. Petroleum is used to make synthetic elastomers. Rubber is frequently referred to as elastomers because of this feature.
Question 7: What is Neoprene?
Answer:
Neoprene, also known as polychloroprene, is a homopolymer formed by the polymerization of chloroprene by free radicals. It is used to create conveyor belts, hoses, and gaskets, among other things, and has a high oil resistance.
Rubber
Rubber is a natural product made by plants. Throughout the history of humanity and the rise of human civilizations, rubber has played a significant role. Today, we obtain 99% of the natural rubber we use from a tree known as Hevea brasiliensis. Hence, rubber is an elastic material produced from the emission of some tropical plants (natural rubber) or extracted from petroleum and natural gas (synthetic rubber). Rubber is an elastic, flexible, and tough substance therefore, it can be used to manufacture tires for vehicles, aircraft, bicycles, etc.
