Application Note

Characterization of Polyketone Copolymer by High Speed DSC


The aliphatic polyketone copolymer (PK copolymer) is a perfectly alternating copolymer of ethylene and carbon monoxide. It exhibits many desirable engineering thermoplastic properties, such as a high tensile yield stress and an excellent impact performance. Its high degree of chemical resistance and superior barrier properties make this polymer an interesting, new thermoplastic for engineering applications. HyperDSC® is the premier fast scan Differential Scanning Calorimetry (DSC) technique from PerkinElmer. This application note demonstrates that HyperDSC technique is really the most effective and most sensitive DSC technique available at the moment for the characterization of both the crystalline and the amorphous phase of a polymeric system.
