MONOFILE AUF DER BASIS VON POLYETHYLEN 2,6- NAPHTHALAT

摘要

Monofilaments based on polyethylene-2,6-naphthalate (PEN) contain 60-99.9 wt% PEN, 0.1-10 wt% liquid crystalline polymer(s) (LCP), 0-15 wt% polybutylene terephthalate (PBT), 0-3 wt% capping agent and optionally other additives. An Independent claim is also included for a process for the production of these monofils by mixing the above components, forming monofilaments from the melt and then cooling and stretching, using extrusion and stretching conditions matched to give monofils with a diameter of 0.08-1.5 mm.
