Abstract
The properties of an adhesive are a function of its adhesive or tacky properties and its cohesive or internal strength properties. Generally, varying the polymer properties to increase the cohesive strength of the adhesive will lower the tack of the adhesive. An improvement in both the cohesive and adhesive properties of an adhesive comprising a polymer and a tackifier by using a polymer which comprises a plastic grafted onto an elastomer; and a tackifier which is more compatible in the elastomer.
