    摘要: A polyesteramide copolymer having a glass transition temperature (Tg) of less than or equal to 0° C., contains at least one hard segment containing at least one amide bond, and at least one soft segment containing at least one ester bond. The soft segment is formed from at least one dimer fatty acid and/or dimer fatty diol and/or equivalent thereof. The copolymer is particularly suitable for use as a hot melt adhesive on low energy surfaces.

    摘要: 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.
