PURPOSE: To provide the title compsn. which has excellent moldability and gives molded products having excellent mechanical strengths, org. solvent resistance and appearance, by melt-kneading a mixture of polycarbonate and polypropylene with a plurality of specific compatibilizers.
CONSTITUTION: The title compsn. is obtd. by melt-kneading a mixture (A) of 10W90wt.% polycarbonate (hereinafter referred to as PC) and 90W10wt.% polypropylene (hereinafter referred to as PP) with 1W50pts. (by weight; the same applies hereinbelow) PC (B) having carboxyl groups at terminals, 1W50pts. PP (C) having carboxyl groups and 0.1W20pts. (per 100pts. of the total amount of the components A and B) at least one metallic compd. (D) capable of supplying a mono-, di- or trivalent metal ion (e.g., MgSO4), each per 100pts. mixture A. By blending the mixture A with a plurality of the above compatibilizers, a compsn. can be obtd. which has excellent mechanical strengths inherent to PC as well as excellent moldability and org. solvent resistance inherent to PP and gives molded products having excellent appearances and in which either one of the resins forming a disperse phase exhibits a fine dispersion of about several microns.
