	Polymer banknote - Wikipedia, the free encyclopedia
		Polymer banknotes were developed by the Reserve Bank of Australia (RBA) and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and were first issued as currency in Australia in 1988.
		The complexities of counterfeiting polymer banknotes are proposed to act as a deterrent to counterfeiters.
		Although the 5 pound Northern Bank polymer banknote was a one-off commemorative issued, unconventionally, in portrait orientation to mark the year 2000, it was in general circulation.

		An addition polymer is one in which the molecular formula of the repeating structural unit is identical to that of the monomer, e.g., polyethylene and polystyrene.
		A condensation polymer is one in which the repeating structural unit contains fewer atoms than that of the monomer or monomers because of the splitting off of water or some other substance, e.g., polyesters and polycarbonates.
		Polymerization, the chemical process of forming polymers from their component monomers, is often a complex process that may be initiated or sustained by heat, pressure, or the presence of one or more catalysts.

	The Effect of Fillers on Adhesion of Polymer Interfaces
		Polymer adhesion is of great current interest in industrial applications, because the joining of polymers can allow one to combine properties of more than one material.
		Therefore, simply joining the polymer slabs when carbon fl is present for a longer period of time may eventually offset the negative effect, and allow for adhesion comparable to that of the pure system.
		Exfoliated clay is known to decrease the permeability of gases in polymers by physically blocking the passage of gas molecules.

	Self Assembly Technique Produces Complex Polymer Structures
		Formation of the structure begins by dissolving a coil-like polymer such as polystyrene in a fast-evaporating solvent such as toluene or benzene.
		The solution containing the dilute (0.1 to 5 percent by weight) polymer is placed on a glass slide, and moist air is directed across it as the solvent evaporates.
		The process repeats itself for one to two minutes until all of the solvent is evaporated, producing a three-dimensional pattern of closely packed water droplets preserved in the polymer film.

	Polymer Analysis - Title
		If a polymer chain is attached to the bond sticking straight up and the chain is attached to one of the legs of the tripod then substitutent groups attached to the other two legs have a choice of being placed to the right or left.
		In many polymers resolution of splittings for individual stereochemical peaks is not possible and this is illustrated by the PVC spectra.
		One reason for studying polymers in solution is that the anisotropy of the magnetic moment with respect to the macromolecule (Chemical Shift Anisotropy, CSA) is averaged out due to thermal motion of the molecule in solution.

		But common to all polymers are long monomer chains in which no two monomers can occupy the same place, i.e., they have an ``excluded volume.'' In other words, polymer chains cannot self-intersect.
		Polymers can become entangled and form messy coils like a length of thread or a shoelace.
		Thus he calculated the free energy of a polymer chain as a sum of the free energy of the real gas and the entropic contribution from the random walk.

		The domains of polymer B are now joined together, but so are the domains of polymer A. When this happens we say that the polymer A phase and the polymer B phase are co-continuous.
		Polymer B is now the major component and polymer A is the minor component, and the situation is reversed from what we had at first.
		When polymer A and polymer B are present in roughly equal amounts, they form two co-continuous phases.

		Polymer runs under Linux, supports IMAP, should support large amounts of mail fast (he says he had a problem there), is standards-compliant, supports as much Unicode as Python does, supports RFC2476, is lightweight (or intended to be), and supports ACAP.
		Finally, Polymer is specifically designed to co-exist with other email clients, by its use of ACAP and IMAP as data storage and access.
		Polymer already compresses the IMAP, ACAP and ESMTP connections if your servers support STARTTLS, and both ends are using OpenSSL 0.9.8, which, as I understand it, does all this automatically.
