Abstract
In the present invention, poly(ester-amide) hot-melt adhesives are prepared from condensation of a mixture of polymeric fatty acids and 1,18-octadecanedicarboxylic acid, and a substantially equivalent proportion of a mixture of a polyamine and a polyol.
Claims4
A poly(ester-amide) adhesive composition which comprises the product of the polymerization of:
- (a) from about 95 to about 40 equivalent percent of a polymeric fatty acid and from about 5 to about 60 equivalent percent of eicosanedioic acid (1,18-octadecanedicarboxylic acid);
- and
- (b) a substantially equivalent amount of from about 30 to about 90 equivalent percent of an organic diamine and from about 70 to about 10 equivalent percent of an organic diol.
