Abstract
By investigation of adhesion following the harmonic mean method after Wu a suitable pair out of seven liquid crystalline (LCP) and conventional polymers was established in order to produce a LCP-matrix compound. Using a bidirectional piston mixer with a steel wire mesh with mesh size of 63 μm, 5% of the picked out PHB-PET copolymer was finely dispersed into the PET matrix polymer in the molten state. As a result a dispersion of the initial volume of the LCP granules of 1 mm3 into small particles of 0.5 to 1.0 μm3 as well as a very uniform local distribution was achieved which can be considered as an argument for the compatibility of the selected pair and as a confirmation of the usefulness of the preceding investigations of adhesion.
