BESTIMMUNG DES SCHMELZFLUSSINDEXES BEI DER POLYMERISATIONSÜBERWACHUNG

摘要

Closed-loop feedback control of (continuous) catalytic polymerisation, by regulating the introduction of a Chain Transfer Agent (CTA) to a reactor, and so polymer chain length formation; through responsive (on-line) MFI determination, of a reactor polymer sample, using an MFI measurement viscometer (70) with dual measurement dies (91, 93), for extended measurement range.
