ABSTRACT:
A method for producing articles of composite resin, wherein a liquid crystal polymer material in powder form is mixed with a second, melt-processable polymer material; the resulting mixture is kneaded at a temperature at which the second polymer material will melt but at which no deformation of the liquid crystal polymer will be caused so as to prepare a blend comprising the liquid crystal polymer powder uniformly dispersed in the matrix of the second polymer; and the blend is then subjected to a molding or shaping process at a temperature within the range at which the liquid crystal polymer is capable of forming liquid crystals.
