ABSTRACT:
The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by using as the adhesive an interpolymer comprising a conjugated diene and a heterocyclic nitrogen base and by using a rubber containing about 5-60 parts of silica filler per 100 parts by weight of rubber, said silica having a purity on an anhydrous basis of at least 95%.
