To provide a molecular composite material having excellent properties such as good mechanical strengths, heat resistance and solvent resistance by kneading a liquid crystal polymer and a polycarbonate under heating to a speci fied temperature.
Ten to 90wt.% liquid crystal polymer (A) comprising a polyazomethine polymer or copolymer of an average-molecular weight of 3,000-100,000 and 90-10wt.% polycarbonate (B) having a molecular weight of 5,000-100,000 and represented by the formula (wherein R1 and R2 are each H or a 10C or lower alkyl) are kneaded under heating to a temperature (usually 250-320°C) equal to or higher than the higher one of the melting points of components A and B and lower than the lower one of their decomposition temperatures for 0.5-60min to obtain a molecular composite material.
