Abstract
A blend of polymers comprising from 5 to 95 weight % of a polymer having a high molecular weight made using a single site type catalyst and from 95 to 5 weight % of a polymer having a lower molecular weight made using a catalyst containing a phenoxide, preferably a salicylaldimine ligand, has an excellent toughness and would be suitable for use in applications such as polyolefin pipes.
