  • Polyolefin-condensation polymer blend
    Patent number: 5849844
    Abstract: A process for the preparation of a plastics blend which contains a polyolefin-condensation polymer blend, in the first step of which process a crystalline polyolefin component and a low-crystallinity polyolefin component are functionalized in one process step by grafting thereto a functional monomer and by pre-dispersing the polyolefins with each other, and in the second step the functionalized polyolefin component is mixed with a condensation polymer and, when so desired, with a non-functionalized olefin polymer, and with other components of the plastics blend.
