Studies on the rotomolding of liquid crystalline polymers

摘要

This paper is concerned with the rotomolding of thermotropic liquid crystalline polymers (TLCPs) for the purpose of generating tank liners with excellent barrier to oxygen. The major issues involved include whether the TLCPs can be ground to provide resins suitable for rotomolding (approx40 mech size powder) and their ability to fuse together to provide adequate strengtha nd barrier properties. With the use of appropriate grinding techniques, the TLCPs were found to fuse well to provide strength and stiffness significantly greater than that of HDPE.
