Abstract
Various blends of polymers are disclosed, comprising oligopeptide functionalised polymers such as polyisobutylene and polystyrene. Mono-functionalised and di-functionalised polymers (each containing 0 to 5 peptide units beyond its terminal amide group) may be blended with each other and/or with non-functionalised polymers to produce blended compositions. Such compositions are of use, for example, in vibrations dampers. Certain blends also exhibit self-healing properties.
Claims26
A polymer blend, comprising:
- a first oligopeptide-terminal polymer component selected from the group consisting of:
- a hydrophobic, flexible polymer having a glass transition temperature below 20° C. and only one monodisperse oligopeptide end group, the monodisperse oligopeptide end group having 1 to 5 amino acid repeating units;
- and
- a hydrophobic, flexible polymer having a glass transition temperature below 20° C. and two monodisperse oligopeptide end groups;
- and
- at least one additional polymer component which includes a hydrophobic, flexible polymer that has a glass transition temperature below 20° C. and is without an oligopeptide end group.
