PETS Model


Preaveraged model for Entangled Telechelic Star polymers: This theory is intended for the prediction of non-linear transient flows of entangled telechelic (with sticky functional groups at the chain-ends) star polymers.

  • Parameters
    • G : Plateau Modulus

    • tau_as : Typical time the sticker spends associated

    • tau_free : Typical time the sticker spends free

    • lmax : Maximum extensibility

    • beta : CCR coefficient

    • delta : CCR exponent

    • Z : Entanglement number

    • r_a : Ratio of sticker size to tube diameter
