ABSTRACT:
A certain class of poly(ester-amide) polymers are disclosed which are particularly suitable as hot melt adhesive compositions particularly advantageous for bonding plastics, such as polyester or polycarbonate polymers. The particular class of poly(ester-amides) are those which include a polymeric fat acid, and more specifically a dimeric fat acid component, in which the ester segments will contribute from about 20, preferably 35 to about 60 weight percent of the poly(ester-amide) and the amide segment contributing the remainder.
