- Abstract
- Compatibility and physical properties of aliphatic polyketon (PK)/polyamide 6 (polyamide, PA) blend were studied. The PK/PA blend showed high interfacial adhesion and impact strength despite the phase-separated morphology. It was observed that PK-PA copolymer formed by the chemical reaction between the two polymers acts as a reactive compatibilizer. The mixing torque for the blends was very high, and the presence of the copolymer was confirmed by FTIR analysis. PA accelerated the crosslinking reaction of PK. The PK/PA blends were prepared under various processing conditions and their impact strength and amount of cross-linked polymer were measured. The impact strength of the blend increased with the amount of the cross-linked polymer. From these results, it was concluded that the reason for the high physical properties of the PK/PA blend is due to the chemical reaction between PK and PA, and the cross-linking reaction of PK promoted by the presence of PA.
