Abstract
Crystallizable hot melt adhesive compositions comprising block copolyesteramides and alkali metal salts of carboxy polymers. The block copolyesteramides comprise hard or crystalline polyester blocks and soft or amorphous polyamide blocks in the weight ratio of 2:3 to 4:1. The alkali metal salts are salts of copolymers of C.sub.1 to C.sub.4 aliphatic olefins and acrylic or methacrylic acid or salts of copolymers of aromatic olefins and maleic anhydride and provide a concentration of alkali metal cation in the range of 0.1 to 15 meq per 100 parts by weight of copolyesteramide. The hot melt adhesive compositions are useful for bonding plastic parts to form plastic structures which are relatively free of bond line distortion.
