pol·y·mer

 (pŏl′ə-mər)
n.
Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units, each a relatively light and simple molecule.

[Greek polumerēs, consisting of many parts : polu-, poly- + meros, part; see (s)mer- in Indo-European roots.]

polymer

(ˈpɒlɪmə) or

polymeride

n
(Elements & Compounds) a naturally occurring or synthetic compound, such as starch or Perspex, that has large molecules made up of many relatively simple repeated units. Compare copolymer, oligomer
polymerism n

pol•y•mer

(ˈpɒl ə mər)

n.
a compound of high molecular weight derived either by the addition of many smaller molecules, as polyethylene, or by the condensation of many smaller molecules with the elimination of water, alcohol, or the like, as nylon.
[1865–70; < Greek polymerḗs having many parts. See poly-, -mer]

pol·y·mer

(pŏl′ə-mər)
Any of various chemical compounds made of smaller, identical molecules (called monomers) linked together. Some polymers, like cellulose, occur naturally, while others, like nylon, are artificial. Polymers have extremely high molecular weights, make up many of the tissues of organisms, and are used to make such materials as plastics, concrete, glass, and rubber. ♦ The process by which molecules are linked together to form polymers is called polymerization (pə-lĭm′ər-ĭ-zā′shən).

polymer

A material containing very large molecules which are built up from a series of small basic units (monomers). There can be between hundreds and hundreds of thousands of basic units in a polymer.

I plan to derive explicit constitutive laws for rubber from polymer chain properties, using the insight of the first two challenges.
This report represents our initial efforts towards synthesizing such nanocomposites with the ability to fully and independently control the structural parameters of polymer chain length and of the spacing of polymer attachments over a broad range.
Key statement: The present invention achieves increased filler interaction by incorporating a small amount (a few units per chain of rubbery polymer) of a conjugated triene monomer, such as alloocimene, randomly throughout the polymer chain of a rubbery polymer or at the chain ends of the rubbery polymer.
We have established that processing can reduce the length of the polymer chain, and this is the primary area of interest when we perform MFR tests on molded parts and the related raw materials.
These radicals then serve as the initiators for polymer chain growth.
The benefit of this process is that the polymer chain grows slowly but steadily, and can be modified at various stages throughout the process to create a polymer with whatever characteristics the end user desires.
Anionic conjugated polymers are promising cation sensors, offering bright fluorescence and superior fluorescence-quenching response upon analyte binding, due to highly efficient intramolecular energy transfer along the polymer chain.
It was noted that all combinations of polymer and Surfynol SE-F caused a rise in surface tension (over that for Surfynol SE-F alone), due to adsorption of surfactant molecules along the polymer chain.
The UV absorber in Vitiva PET is chemically bound to the polymer chain, which enables bottle manufacturers and brand owners to more easily obtain consistent UV performance.
In addition, the time scale that controls polymer chain relaxation has taken on a new importance as nanotechnology polymer innovation evolves from three dimensions to two.
Because polymers are made up of very long chains of atoms, the scientists were able to see bright spots along the polymer chain as electrons flowed back and forth.
