Beschreibung
Zusammenfassung:	Age resistant resin which comprises a composition selected from (A) a composition having a softening point in the range of 0 DEG C to about 140 DEG C comprising units derived from selected aliphatic diolefins and aliphatic monoolefins, which can be modified with units derived from dicyclopentadiene, and certain vinyl aromatic compounds, and selected phenol or amine type compounds and (B) a composition having a softening point in the range of about 60 DEG C to about 110 DEG C comprising units derived from monoolefins and vinyl aromatic compounds, which can be modified with aliphatic diolefins, and selected phenol and amine type compounds. Such age resistant resins have particular utility when admixed with various rubbery materials and thermoplastics to create pressure sensitive adhesives and hot melt adhesives.
