What are the natural polymers?

Polymers are encountered in everyday life and are used for many purposes! Polymers are chains made of monomer subunits. For instance, poly(vinyl chloride) is a strong, corrosion-resistant polymer commonly used in plumbing applications, whereas polyethylene is an example of a flexible polymer found in plastic bags.

The most important primary sources of synthetic polymers are crude oil, natural gas and, to a minor extent, coal. Because all are primarily fuels rather than sources of materials, the manufacture of polymers is susceptible to changes in price or supply.

It is a polymer that consists of repeating units of the monomer CH2CH(CO2Na)- or (C3H3NaO2)n. The n stands for any number of molecules. Common table salt is mainly made up of the compound sodium chloride. The chemical formula for sodium chloride is NaCl.

The human body contains many natural polymers, such as proteins and nucleic acids. Cellulose, another natural polymer, is the main structural component of plants. Most natural polymers are condensation polymers, and in their formation from monomers water is a by-product.

The eight most common types of synthetic organic polymers, which are commonly found in households are:

Low-density polyethylene (LDPE)

High-density polyethylene (HDPE)

Polypropylene (PP)

Polyvinyl chloride (PVC)

Polystyrene (PS)

Nylon, nylon 6, nylon 6,6.

Teflon (Polytetrafluoroethylene)

Thermoplastic polyurethanes (TPU)

Natural Rubber. Natural rubber is an addition polymer that is obtained as a milky white fluid known as latex from a tropical rubber tree. Natural rubber is from the monomer isoprene (2-methyl-1,3-butadiene), which is a conjugated diene hydrocarbon as mentioned above.

Plastics and natural materials such as rubber or cellulose are composed of very large molecules called polymers . Polymers are constructed from relatively small molecular fragments known as monomers that are joined together.

When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.

Rayon was the first manufactured fiber. The term rayon was officially adopted by the textile industry. Unlike most man-made fibers, rayon is not synthetic. It is made from wood pulp, a naturally-occurring, cellulose-based raw material.

Cotton is a linear, cellulose polymer. The repeating unit in the cotton has two glucose units, called cellobiose. Cotton consists of about 5000 cellobiose units. Its degree of polymerization is thus 5000.

They are composed of nucleotides, which are monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base. If the sugar is a compound ribose, the polymer is RNA (ribonucleic acid); if the sugar is derived from ribose as deoxyribose, the polymer is DNA (deoxyribonucleic acid).

DNA is considered as a polymer because it is made up of so many nucleotides ( 1 nitrogenous base + 1 pentose sugar + 1 phosphate group = 1 Nucleotide ) joined together through phosphodiester bonds . So DNA is a polynucleotide chain . A polymer is defined as a large molecule composed of repeated subunits.

Common examples. Polymers are of two types: naturally occurring and synthetic or man made. Natural polymeric materials such as shellac, amber, wool, silk and natural rubber have been used for centuries. A variety of other natural polymers exist, such as cellulose, which is the main constituent of wood and paper.

Glycogen is the analogue of starch, a glucose polymer that functions as energy storage in plants. It has a structure similar to amylopectin (a component of starch), but is more extensively branched and compact than starch. Both are white powders in their dry state.

Perhaps the “semi-synthetic” polymers that was stated in the question refers to this kind of polymers. For example, cellulose acetate is a thermoplastic polymer that is produced from cellulose, a natural polymer, rather than through polymerization reaction of a monomer.

Polystyrene (PS) /ˌp?liˈsta?riːn/ is a synthetic aromatic hydrocarbon polymer made from the monomer styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. Polystyrene can be naturally transparent, but can be coloured with colourants.

Amino acids are the structural units (monomers) that make up proteins. They join together to form short polymer chains called peptides or longer chains called either polypeptides or proteins. These polymers are linear and unbranched, with each amino acid within the chain attached to two neighboring amino acids.

Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melt-processed into fibers, films or shapes. Nylon is made of repeating units linked by peptide bonds.

Glass is a state of materials containing but not limited to polymers, so is crystal. Therefore glass will never be categorized as crystal. Both glass and crystalline states are observed in polymers. Polymers in glass state only behave as solids within the common time period of human.

What’s the difference between natural and synthetic fabrics? Natural fabrics, like merino wool, cotton, cashmere, and silk, are made of fibers that are produced by animals and plants. Synthetic fabrics, like polyester, nylon and acrylic, are “man-made” fibers that are created in laboratories.
