ABSTRACT OF THE DISCLOSURE Poly(ester-amide) adhesive compositions comprising a finely divided spheroidal metal. The poly(ester-amide) comprises crystalline polyester and amorphous polyamide segments formed by reaction of a C18 to C54 polycarboxylic acid mixture and a C2 to C10 aliphatic or alicyclic primary diamine. The finely divided spheroidal metal is selected from the group consisting of aluminum, iron, mild steel, stainless steel and zinc. The weight ratio of poly(ester-amide) to metal is in the range of 70:30 to 30:70. The adhesive compositions are useful as hot melt adhesives and cavity fillings.
