  2. Polymer - Wikipedia

    en.wikipedia.org/wiki/Polymer

    Polymer nomenclature is generally based upon the type of monomer residues comprising the polymer. A polymer which contains only a single type of repeat unit is known as a homopolymer, while a polymer containing two or more types of repeat units is known as a copolymer. [22] A terpolymer is a copolymer which contains three types of repeat units ...

  3. Polymer chemistry - Wikipedia

    en.wikipedia.org/wiki/Polymer_chemistry

    Polymer chemistry is a sub-discipline of chemistry that focuses on the structures, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry , analytical ...

  4. Monomer - Wikipedia

    en.wikipedia.org/wiki/Monomer

    Chemistry classifies monomers by type, and two broad classes based on the type of polymer they form. By type: natural vs synthetic, e.g. glycine vs caprolactam, respectively; polar vs nonpolar, e.g. vinyl acetate vs ethylene, respectively; cyclic vs linear, e.g. ethylene oxide vs ethylene glycol, respectively; By type of polymer they form:

  5. Polymerization - Wikipedia

    en.wikipedia.org/wiki/Polymerization

    In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. [1] [2] [3] There are many forms of polymerization [4] and different systems exist to categorize them.

  6. Topochemical polymerization - Wikipedia

    en.wikipedia.org/wiki/Topochemical_polymerization

    Schematic diagram of topochemical polymerization, the monomer is first crystallized and polymerized to give the polymer product. Topochemical polymerization is a polymerization method performed by monomers aligned in the crystal state. In this process, the monomers are crystallised and polymerised under external stimuli such as heat, light, or ...

  7. IUPAC polymer nomenclature - Wikipedia

    en.wikipedia.org/wiki/IUPAC_polymer_nomenclature

    Polymer nomenclature usually applies to idealized representations meaning minor structural irregularities are ignored. A polymer can be named in one of two ways. Source-based nomenclature can be used when the monomer can be identified. Alternatively, more explicit structure-based nomenclature can be used when the polymer structure is proven.

  8. Functionality (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Functionality_(Chemistry)

    Thus in the case of a functionality of f = 2 a linear polymer is formed by polymerizing (a thermoplastic). Monomers with a functionality f ≥ 3 lead to a branching point, which can lead to cross-linked polymers (a thermosetting polymer). Monofunctional monomers do not exist as such molecules lead to a chain termination. [6]

  9. Degree of polymerization - Wikipedia

    en.wikipedia.org/wiki/Degree_of_polymerization

    The degree of polymerization, or DP, is the number of monomeric units in a macromolecule or polymer or oligomer molecule. [1] [2] [3]For a homopolymer, there is only one type of monomeric unit and the number-average degree of polymerization is given by ¯ ¯ = ¯, where ¯ is the number-average molecular weight and is the molecular weight of the monomer unit.
