  2. Liquid-crystal polymer - Wikipedia

    en.wikipedia.org/wiki/Liquid-crystal_polymer

    Lyotropic main chain LCPs have been mainly used to generate high-strength fibers such as Kevlar. Side chain LCPs usually consist of both hydrophobic and hydrophilic segments. Usually, the side chain ends are hydrophilic. When they are dissolved in water, micelles will form due to hydrophobic force. If the volume fraction of the polymers exceeds ...

  3. Branching (polymer chemistry) - Wikipedia

    en.wikipedia.org/wiki/Branching_(polymer_chemistry)

    In polymer chemistry, branching is the regular or irregular attachment of side chains to a polymer's backbone chain. It occurs by the replacement of a substituent (e.g. a hydrogen atom) on a monomer subunit by another covalently-bonded chain of that polymer; or, in the case of a graft copolymer, by a chain of another type.

  4. Peptide - Wikipedia

    en.wikipedia.org/wiki/Peptide

    [1] [2] A polypeptide is a longer, continuous, unbranched peptide chain. [3] Polypeptides that have a molecular mass of 10,000 Da or more are called proteins. [4] Chains of fewer than twenty amino acids are called oligopeptides, and include dipeptides, tripeptides, and tetrapeptides.

  5. Peptide synthesis - Wikipedia

    en.wikipedia.org/wiki/Peptide_synthesis

    The solid support consists of small, polymeric resin beads functionalized with reactive groups (such as amine or hydroxyl groups) that link to the nascent peptide chain. [2] Since the peptide remains covalently attached to the support throughout the synthesis, excess reagents and side products can be removed by washing and filtration.

  6. Peptide bond - Wikipedia

    en.wikipedia.org/wiki/Peptide_bond

    Peptide bond formation via dehydration reaction. When two amino acids form a dipeptide through a peptide bond, [1] it is a type of condensation reaction. [2] In this kind of condensation, two amino acids approach each other, with the non-side chain (C1) carboxylic acid moiety of one coming near the non-side chain (N2) amino moiety of the other.

  7. Living polymerization - Wikipedia

    en.wikipedia.org/wiki/Living_polymerization

    However, there is a key difference, following reductive elimination in CTP, an associative complex is formed (which has been supported by intra-/intermolecular oxidative addition competition experiments [8]) and the subsequent oxidative addition occurs between the metal center and the associated chain (an intramolecular pathway). Whereas in a ...

  8. Sandwich-structured composite - Wikipedia

    en.wikipedia.org/wiki/Sandwich-structured_composite

    The interface between the core and the skin: Because the shear stresses in the composite material change rapidly between the core and the skin, the adhesive layer also sees some degree of shear force. If the adhesive bond between the two layers is too weak, the most probable result will be delamination.

  9. Condensation polymer - Wikipedia

    en.wikipedia.org/wiki/Condensation_polymer

    Condensation polymers are formed by polycondensation, when the polymer is formed by condensation reactions between species of all degrees of polymerization, or by condensative chain polymerization, when the polymer is formed by sequential addition of monomers to an active site in a chain reaction.
