✦ Synopsis

In this work, a virgin Rodrun LC-5000 liquid crystalline polymer was recycled several times by an injection moulding process. The results showed that there is a signi®cant decrease in the Young's modulus and the tensile strength after the recycling operation, while there is almost no change in the tensile strain. A power law relationship was established between the melt ¯ow rate of the recycled resin and the number of recycling stages. The characteristic three-layer, skin-transition-core structure of the injection moulded specimens was also found to be altered by the number of recycling stages.
