    Patent number: 4548996
    Abstract: Crystallizable hot melt adhesive compositions comprising block copolyesteramides and alkali metal carboxylates. 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 carboxylates provide a concentration of alkali metal cation in the range of 0.1 to 6 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.
