If the polymer chain assumes a helicoidal conformation in the crystalline state, and if it does not contain asymmetric carbon atoms, it can be expected that either helices of the same sense, or, in equal ratio, helices of opposite sense are represented in the lattice.

Polymeric materials in the form of wood, bone, skin and fibers have been used by man since prehistoric time. Although organic chemistry as a science dates back to the eighteenth century, polymer science on a molecular basis is a development of the twentieth century.

Polymer chemistry provides an excellent means of studying metathesis catalysts: miniscule catalyst loadings have the capacity to generate large amounts of polymeric material, the structure of which can provide a historical record of catalyst activity.

American Scientist

Polymer synthesis in the 1950s was dominated by Karl Ziegler and Giulio Natta, whose discoveries of polymerization catalysts were of great importance for the development of the modem 'plastics' industry.

In spite of the evidence for the disorder-induced M-I transition as inferred from the transport and optical measurements, the metallic state of conjugated polymers has been a subject of controversy.

Nature works with five polymers. Only five polymers. In the natural world, life builds from the bottom up, and it builds in resilience and multiple uses.

In 1957, at the age of 18, I entered Kyoto University, which was known to be the most active institution in the research of polymer chemistry.

Japanese Scientist

The science of semiconducting and metallic polymers is inherently interdisciplinary; it falls at the intersection of chemistry and physics.

Like the Tebbe complex, ruthenium olefin metathesis catalysts can be used for the production of living polymers.

All vinyl polymers may be regarded as built from monomeric units containing a tertiary carbon atom.

The term 'polymer' is often used in science and engineering to discuss materials' properties.

Scientific Context

Imagine polymers like LEGO bricks, connecting many small pieces to create a larger structure.

Building Block Analogy

A polymer is formed from monomers, which are the smaller molecules that link together.

Monomer Link

In academic contexts, 'polymer' usually relates to the study of substances for scientific research or industrial application.

Academic Use

Polymers have diverse uses, fundamental in everything from fashion to electronics.

Versatile Applications

The development of new polymers can lead to breakthroughs in material science and technology.

Material Innovation

 we're getting incredible yield rates. Natural polymers, well ... I think that's what's most important, because these polymers have been tried and tested in our ecosystem for the last billion years, in everything from mushrooms to crustaceans. They're not going to clog up Earth's ecosystems. They work great. And while, today,

 They're polymers. Polymers are such a big part of our lives that it's virtually impossible to imagine a world without them, but what the heck are they? Polymers are large molecules made of small units called monomers linked together like the railroad cars from a train.
