Natural rubber - Wikipedia
Rubber is a natural polymer of isoprene (polyisoprene), and an elastomer (a stretchy polymer). Polymers are simply chains of molecules that can be linked together. Rubber is one of the few naturally occurring polymers and prized for its high stretch ratio, …
Rubber Chemistry - HowStuffWorks
Like plastic, rubber is a polymer, which is a chain of repeating units called monomers. In rubber, the monomer is a carbon compound called isoprene that has two carbon-carbon double bonds. The latex fluid that seeps from rubber trees has many isoprene molecules. As the latex dries, the isoprene molecules crowd together and one isoprene molecule ...
Rubber Polymers - Chemistry LibreTexts
2023年1月23日 · The majority of rubber polymer molecules contain at least some units derived from conjugated diene monomers (see Polymerization of Conjugated Dienes). Such conjugated diene monomers have a constructive backbone of at least four carbon atoms with a double-single-double bond reactive core (C=C-C=C ).
Rubber | Tropical Plants, Petroleum, & Natural Gas | Britannica
rubber, elastic substance obtained from the exudations of certain tropical plants (natural rubber) or derived from petroleum and natural gas (synthetic rubber). Because of its elasticity, resilience, and toughness, rubber is the basic constituent of the tires used in …
Rubber - Chemistry Encyclopedia - structure, reaction, water, uses ...
Rubber is an elastomer—that is, a polymer that has the ability to regain its original shape after being deformed. Rubber is also tough and resistant to weathering and chemical attack.
Rubber Molecule - an overview | ScienceDirect Topics
Rubber is a hydrocarbon polymer produced by many tropical and a few temperate plants, such as the dandelion. Commercially, rubber is obtained from a tree originally found in Brazil, Hevea brasiliensis, which is now grown extensively in southeast Asia and Africa, as …
Molecular Structure of Natural Rubber and Its ... - IntechOpen
2012年3月14日 · 2.3. Structural change of rubber molecule in rubber tree. Rubber tapped from the first opening mature tree, also known as virgin tree, contains a solvent-insoluble fraction formed via carbon–carbon linkages that are referred to as ‘hard-gel’, as high as 80–90% of whole solid rubber. This gel fraction showed the structure and cross ...
Natural Rubber: Structure and Function - Halcyon
Natural rubber is a polymer, a long, chain like molecule that contains repeating subunits. The term polymer comes from the Greek “poly” meaning many and “mer” meaning parts. The chemical name for natural rubber is polyisoprene.
How Rubber Works - HowStuffWorks
Rubber is an elastomer, a large molecule that can be stretched and returned to its original shape. Learn why rubber is so stretchy and how we make it.
Rubber Molecular Characteristics - Schirnfel
Rubber’s molecular structure has unique traits: I. They are long chain molecules composed of repeating units (chain links). They have a flexible chain segment and a glass transition temperature (Tg) less than room temperature. II.
