A molecule composed of a small number of linked monomer units; a short polymer; -- compounds called oligomers have less than one hundred monomer units and usually less than thirty. Oligomers of increasing length are called dimer, trimer, tetramer, pentamer, hexamer, heptamer, octamer, nonamer, decamer, etc. In colloquial laboratory jargon, they may also be referred to as nine-mer, ten-mer, eleven-mer, twelve-mer, etc., especially for oligomers of greater than eight units.
Oligomer is a substance consisting of molecules of intermediate relative molecular mass (molecular weight), the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass. In contrast to a polymer, the properties of an oligomer can vary significantly with the removal of one or a few of its units.
Gr.: a few units] • A compound molecule of intermediate size, made up of two to a few monomers. (Contrast with monomer, polymer.)
A Simple Polymer Containing A Small Number Of Repeating Units., Note: The Oligomer Most Frequently Encountered In The Textile Industry Is The Cyclic Trimer Of Poly(ethylene Benzene-1,4-dicarboxylate) (poly(ethylene Terephthalate)), The Polymer Used For Polyester Fibre. This Material Can Form Deposits During The Processing And Dyeing Of Yarns And Fabrics.
A molecule containing a small number of covalently linked units; a multisubunit protein.
a polymer that consists of two, three, or four monomers.
Short polymer, usually consisting (in a cell) of amino acids (oligopeptides), sugars (oligosaccharides), or nucleotides (oligonucleotides). (From Greek oligos, few, little.)
a molecule which is formed from a few smaller (identical) molecules joined together
a single chain that is several thousand monomers long
A multiple unit molecule consisting of several mononumeric units chemically combined. Used in formulating U.V. curable coatings.
a polymer whose molecular weight is too low to really be considered a polymer. Oligomers have molecular weights in the hundreds, but polymers have molecular weights in the thousands or higher.
A molecule that consists of repeating molecular subunits--essentially a polymer but not as long. By analogy, if a yellow brick is a single subunit, the yellow brick road is a polymer, and the yellow brick driveway is an oligomer.
long chain of monomers of length ~50. Compare to polymers.
(r) a polymer consisting of only a few monomer units, such as a dimer, trimer, tetramer, etc., or their mixtures.
a low molecular weight polymer in which the number of repeating units is approximately between two and ten.
A polymer containing a small number of repeating units. Note.. The oligomer most frequently encountered in the textile industry is the cyclic trimer of ethylene terephthalate, which is the repeating unit of the polymer used for the most important of the polyester fibres. This material can form undesirable deposits during the physical processing and dyeing of yarils and fabrics.
In chemistry, an oligomer consists of a finite number of monomer units (Î¿Î»Î¹Î³Î¿Ï‚, or oligos, is Greek for "a few"), in contrast to a polymer which, at least in principle, consists of an unbounded number of monomers.
