Summary

Oligo-and co-oligoamides (Table 1) intended to have M of ca. 20 0 0 g/mol, terminated with carboxyl groups on eitherend, were prepared by reacting a salt of hexamethylene diamine with adipic acid, caprolactam and laurolactam. Tm LVN, and -COOH and -NH2 end-groups were determined in the oligomers (Table 4) and Mn was evaluated. The oligomers were incorporated as hard segments into terpoly(ester-b-ether-b-amide)s and progress of the condensation polymerization was followed in terms of LVN.
