Abstract Hot melt adhesives having improved pot lives and pro- cesses for their preparation Hot melt adhesive compositions having longer pot lives and comprising adhesive thermoplastic compositions having high cohesion and low flowability based on copolymers A) composed of ethylenically unsaturated monomers containing chelating metal compounds B) and, if desired, other conventional additives C), these hot melt adhesive compositions additionally containing an alkylphenolic resin or an arylphenolic resin in amounts of up to 20% by weight, relative to copolymer A), as crosslinking regula- tor in order to extend the pot life and to improve their processibility like a thermoplastic, and processes for preparing hot melt adhesive compositions by mixing the starting components.
