摘要: Hot melt adhesives which include at least 5% of a thermoplastic elastomer block copolymer having a Vicat softening temperature of at least 60.degree. C. and a melting point of at least 100.degree. C., have improved thermal resistance properties and can be applied with conventional hot melt application equipment at temperatures of between about 149.degree. C. and about 204.degree. C. The adhesives are particularly suited to use in above-the-belt locations in automobile interiors and in furniture bonding. Especially suitable thermoplastic elastomers are polyether-polyester and polyether-polyamide segmented polymers with melting points above 149.degree. C. Hot melt adhesives based on these thermoplastic elastomers can be formulated to provide a range of properties including pressure sensitive properties and contact adhesive properties.
