  2. Monomer - Wikipedia

    en.wikipedia.org/wiki/Monomer

    Epoxide monomers may be cross linked with themselves, or with the addition of a co-reactant, to form epoxy; BPA is the monomer precursor for polycarbonate; Terephthalic acid is a comonomer that, with ethylene glycol, forms polyethylene terephthalate. Dimethylsilicon dichloride is a monomer that, upon hydrolysis, gives polydimethylsiloxane.

  4. Polymerization - Wikipedia

    en.wikipedia.org/wiki/Polymerization

    Other monomer units, such as formaldehyde hydrates or simple aldehydes, are able to polymerize themselves at quite low temperatures (ca. −80 °C) to form trimers; [3] molecules consisting of 3 monomer units, which can cyclize to form ring cyclic structures, or undergo further reactions to form tetramers, [3] or 4 monomer-unit compounds.

  5. Functionality (chemistry) - Wikipedia

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

    According to IUPAC, the functionality of a monomer is defined as the number of bonds that a monomer's repeating unit forms in a polymer with other monomers. Thus in the case of a functionality of f = 2 a linear polymer is formed by polymerizing (a thermoplastic).

  6. Mayo–Lewis equation - Wikipedia

    en.wikipedia.org/wiki/Mayo–Lewis_equation

    If both ratios are near 1, a given monomer will add the two monomers with comparable speeds and a statistical or random copolymer is formed. r 1 ≈ r 2 ≈ 0 {\displaystyle r_{1}\approx r_{2}\approx 0\,} If both values are near 0, the monomers are unable to homopolymerize.

  7. Polymer chemistry - Wikipedia

    en.wikipedia.org/wiki/Polymer_chemistry

    The simple reactive molecule from which the repeating structural units of a polymer are derived is called a monomer. A polymer can be described in many ways: its degree of polymerisation , molar mass distribution , tacticity , copolymer distribution, the degree of branching , by its end-groups , crosslinks , crystallinity and thermal properties ...

  8. Macromonomer - Wikipedia

    en.wikipedia.org/wiki/Macromonomer

    In polymer chemistry, a macromonomer (or macromer) is a macromolecule with one end-group that enables it to act as a reactive monomer and undergo further polymerization. Macromonomers will contribute a single repeat unit to a chain of the completed macromolecule.

  9. Expanding monomer - Wikipedia

    en.wikipedia.org/wiki/Expanding_monomer

    Expanding monomers can not just be homopolymerized as it is shown here but also copolymerized with other monomers to counteract their shrinking. Usually a Lewis acid like boron trifluoride etherate is used for both, the synthesis of the orthoester and the polymerization. The same applies for spiro orthocarbonates and bicyclic orthoesters.
