Guidelines for Rheological Characterization of Polyamide Melts (IUPAC Technical Report)
Guidelines for Rheological Characterization of Polyamide Melts (IUPAC Technical Report)
by Dick J. Dijkstra
Pure and Applied Chemistry, 2009
Vol. 81, No. 2, pp. 339–349
Most producers of polyamide have their own characterization methods to study the rheological properties of polyamide 6 (PA6). However, the measured rheological properties depend strongly on the sample preparation method, humidity regulation, and time-temperature history during the measurement, not to mention the kind of rheometer being used. This investigation is the result of an IUPAC project initiated by the Subcommittee on Structure and Properties of Commercial Polymers (project 2004-009-1-400). Members of several industrial organizations, universities, and institutes cooperated, with the aim of formulating a guideline to measure reproducible rheological properties of PA6. The results of the investigation show the changes in molecular weight during different kinds of rheological measurements due to hydrolysis and amidization reactions. A guideline is introduced that can be used to make comparable rheological measurements on PA6.
