Pr. Hornsby et al., CHARACTERIZATION OF POLYAMIDE-6 MADE BY REACTIVE EXTRUSION .1. SYNTHESIS AND CHARACTERIZATION OF PROPERTIES, Journal of applied polymer science, 53(7), 1994, pp. 891-897
The anionic, polymerisation of epsilon-caprolactam in a corotating, in
termeshing twin-screw extruder is discussed in terms of the materials
formulation, extruder screw profile, and processing parameters such as
temperature and screw speed. Using a variety of analytical characteri
zation techniques, it is demonstrated that molecular mass, residual mo
nomer content, and mechanical properties of the polyamide 6 are very s
ensitive to the reactive processing conditions employed. (C) 1994 John
