Abstract
Abstract Hot melt compositions having low melt viscosity and high adhesive strength, especially to metals, are disclosed. The compositions include a copolyester derived from a glycol having from 2 to 10 carbon atoms, terephthalic acid and dimer acid, blended with a polymeric material comprising a vinyl aromatic polymer derived from a monomer of the formula D R A W I N G
