Both the American Chemical Society (ACS)[61] and IUPAC[62] have proposed standardized naming conventions; the ACS and IUPAC conventions are similar but not identical. For example, a copolymer of polylactic acid and polyglycolic acid is employed in hydrolysable stitches that slowly degrade after they are applied to a wound. { bidder: 'sovrn', params: { tagid: '446382' }}, A simple example is polyethylene ('polythene' in British English), whose repeating unit is based on ethylene monomer. { bidder: 'ix', params: { siteId: '195467', size: [300, 250] }}, When a polymer is dispersed or dissolved in a liquid, such as in commercial products like paints and glues, the chemical properties and molecular interactions influence how the solution flows and can even lead to self-assembly of the polymer into complex structures. [63] Examples of the differences between the various naming conventions are given in the table below: In both standardized conventions, the polymers' names are intended to reflect the monomer(s) from which they are synthesized (source based nomenclature) rather than the precise nature of the repeating subunit. Molten material tends to flow or drip and will propagate fire. For example, the structure of a crystalline protein or polynucleotide, such as a sample prepared for x-ray crystallography, may be defined in terms of a conventional unit cell composed of one or more polymer molecules with cell dimensions of hundreds of angstroms or more. From the strand of our DNA which is a naturally occurring biopolymer to polypropylene which is … }); { bidder: 'criteo', params: { networkId: 7100, publisherSubId: 'cdo_topslot' }}, { bidder: 'pubmatic', params: { publisherId: '158679', adSlot: 'cdo_rightslot' }}]}, How to say Acrylates polymer in English? An important microstructural feature of a polymer is its architecture and shape, which relates to the way branch points lead to a deviation from a simple linear chain. name: "pbjs-unifiedid", { bidder: 'appnexus', params: { placementId: '11654208' }}, These type of lasers, that also belong to the class of organic lasers, are known to yield very narrow linewidths which is useful for spectroscopy and analytical applications. Failure of safety-critical polymer components can cause serious accidents, such as fire in the case of cracked and degraded polymer fuel lines.
