ABSTRACT:
Polyamide graft-modified rubbery block copolymer compositions are provided by reaction of maleated rubbery block copolymers with polymeric dimer fatty acid based polyamide wherein the molar ratio of maleated rubbery block copolymer to the dimer fatty acid polyamide is greater than 2 to 1. The compositions find use as hot melt adhesive components.
