Although being more durable than the old paper notes, polymer notes are just as light and convenient as notes always were.

Large organic molecule formed by combining many smaller molecules (monomers) in a regular pattern.
another word for a plastic material, one which has been made from chains of molecules of one or more MONOMERS.
A large molecule consisting of recurring units of a smaller molecule. A polymer can be thought of as a molecular chain, in which small molecules called monomers form the links.
A substance consisting of molecules characterized by repetition (neglecting ends, branches, junctions, and other minor irregularities) of one or more chemically bonded types of monomeric units. A giant, long chain of molecules having extremely high molecular weights made up of many repeating smaller units called monomers or commoners.
A naturally occurring or synthetic molecule made up of a linked series of repeated simple monomers (smaller molecules, simple compounds). find all NHC pages containing: polymer
Polymer is a term used to describe large molecules consisting of repeating structural units, or monomers, connected by covalent chemical bonds. The term is derived from the Greek words: polys meaning many, and meros meaning parts http://www.etymonline.com/index.php?l=p&p=23. A key feature that distinguishes polymers from other molecules is the repetition of many identical, similar, or complementary molecular subunits in these chains.
an aromatic polyester known generically as PTT, (polytrimethylene terephthalate)
a unique product in that it behaves very differently than other polyesters
A form of LiOn battery that is 20 percent lighter than traditional LiOn and requires less volume. These batteries can be as thin as 6.77 millimeters Also known as LIP (Lithium-Ion Polymer). First seen with the Motorola Elite Analog phone, the battery was 400mah and the wholesale cost when released was 187.50. The battery retailed for about $350 and had a talk time of about 25 minutes so it was not very popular. Today Lion Polymer is mainstream and a very good type of cell to look for, some polymer batteries can exceed 30 days for standby time.
