Combinations of conductive polymeric finely divided conductive material selectively located in the continuous polymer phase or at the continuous interface.

摘要

A conductive polymer blend comprising: (a) at least two polymers which are at least partially immiscible with each other, and are present in proportions such that each polymer forms a respective continuous phase and the two respective continuous polymer phases are co-continuous with each other in the polymer blend; and (b) at least one conductive material in particulate or fiber form which is substantially in one of said co-continuous polymer phases or substantially localized at a continuous interface between said co-continuous polymer phases, wherein said at least two polymers are a pair selected from the following pairs of polymers: HDPE / TPU HDPE / EPR HDPE / EPDM HDPE / mLLDPE PP / EPDM PP / EPR PP / mLLDPE mLLDPE / EPR wherein HDPE: high density polyethylene TPU: thermoplastic urethane EPR: ethylene propylene rubber EPDM of: rubber, ethylene propylene diene mLLDPE: linear low density polyethylene metallocene-catalysed PP: polypropylene.
