Abstract
The present invention relates to blends of poly(ether ketone ketone) (PEKK) polymers, in particular to certain blends endowed with lower melting point than traditional PEKK polymers, yet maintaining high crystallinity and rapid crystallization behaviour, which are composed of a major amount of a first nucleophilic PEKK having a first T/I ratio, and a minor amount of a second PEKK having a second T/I ratio higher than the first T/I ratio; to methods of making the same, and to uses thereof in various fields.
