Abstract
The effect of spherulite growth (diameter 25 to 185 µ) on the adhesive properties and density of polypropylene is studied. The adhesive properties are evaluated in terms of “adhesive power” and “adhesion susceptibility.” It is shown that, as distinct from the cohesive strength, the strength of adhesive joints in which polypropylene is used as substrate and SKB butadiene elastomer as adhesive increases somewhat with the diameter of the spherulites, while the density of the polypropylene increases linearly. It is suggested that the observed increase in adhesion susceptibility is due to surface development associated with the growth of the spherulites.
