Block copolyetheramides were prepared by incorporating polyether into polyamide through melt polycondensation of polyetherdiamine, piperazine, dimer acid, and ε‐caprolactam. Bulk properties of block copolyetheramide, such as tensile strength, tensile modulus, elongation at break, hardness, and impact strength, were evaluated with respect to composition. Investigation on the lap shear strength and T‐peel strength of block copolyetheramide hot melt adhesive showed that the lap shear strength was more composition‐dependent. Moisture and elevating test temperature also reduced the lap shear strength significantly.
