混炼过程电导率分子结构炭黑分散渗透采用在线测定混炼过程电导率的方法，表征了橡胶基体分子结构对炭黑（CB）在胶料中分散的影响。在所有研究的体系中，在线电导率、橡胶对炭黑聚集体的渗透率和炭黑分散值都有相应的变化。线性链结构和低分子量阿萨基体橡胶加速了渗透过程，因此炭黑分散过程发生得更快。用官能团改性橡胶引起的低链运动性导致CB渗透的减速。
Mixing process Electrical conducti-vity Molecular structure Carbon blackdispersion InfiltrationThe influence of molecular structure ofthe rubber matrix on the carbon black(CB) dispersion in rubber compounds hasbeen characterized using the method ofthe online measured electrical conduc-tivity during the mixing. A correspondingchange of the online conductivity, therubber infiltration into the CB agglom-erates, and the CB dispersion value in allthe systems investigated has been ob-served. A linear chain structure as well asa low molecular weight of the matrixrubber accelerates the infiltration pro-cess and hence the carbon black disper-sion process takes place faster. A lowerchain mobility caused by a modificationof the rubber with functional groupsleads to a deceleration of the CB infil-tration.
