  • Controlled Long Chain Branching in EPDM by Post-Reactor Modification
    Publication number: 20220275121
    Abstract: The present disclosure provides a process. In an embodiment, the process includes providing a neat ethylene/ propy-lene/non-conjugated polyene terpolymer (n-terpolymer) having a Mooney viscosity (ML (1+4) at 125C) less than 100 Mooney units (MU). The process includes exposing the n-terpolymer to electron beam radiation at a dosage from 0.2 megaRad (MRad) to 1.3 MRad. The process includes forming a branched ethylene/propylene/non-conjugated polyene terpolymer (b-terpolymer) having a Mooney viscosity ML (1+4) at 125C from 25 MU to 135 MU.

  • EPDM Blends with Long Chain Branching
    Publication number: 20220251360
    Abstract: The present disclosure provides a composition. In an embodiment, the composition includes a non-irradiated ethylene/propylene/non-conjugated polyene terpolymer (nr-terpolymer) and a branched ethylene/propylene/non-conjugated polyene terpolymer (b-terpolymer). The b-terpolymer has: (A) a Mooney viscosity (ML 1+4 @ 125° C.) from 35 MU to 120 MU; (B) a rheology ratio from 55 to 110; and (C) a phase angle ? from 20° to 39°.
