Polyketone-PVC polymer blends

A polymer blend composition comprises a polyketone and PVC provided that the polyketone is not a propylene/CO copolymer having a molecular weight of less than 10,000. The softening point of PVC can be increased by blending with polyketones. Blends of polyketones and unplasticised PVC are particularl...

Zusammenfassung:	A polymer blend composition comprises a polyketone and PVC provided that the polyketone is not a propylene/CO copolymer having a molecular weight of less than 10,000. The softening point of PVC can be increased by blending with polyketones. Blends of polyketones and unplasticised PVC are particularly preferred.
