Abstract

There is provided a polymer composition comprising a first polymer phase and a second polymer phase, wherein: a) the first polymer phase comprises a thermoplastic polymer matrix modified with an adhesive functional group or a group which is a precursor of an adhesive functional group; and b) the second polymer phase comprises a thermoplastic polymer capable of acting as a self-healing agent and being chemically reactive on healing of the polymer composition.
