The Effect of Tackifier on the Properties of Pressure-Sensitive Adhesives Based on Styrene–Butadiene–Styrene Rubber

Аннотация

Pressure-sensitive polymer adhesives based on styrene–butadiene–styrene rubbers and aromatic petroleum hydrocarbon resins making the block copolymer tacky and differing in the degree of hydrogenation were prepared. The rheology of the resins and blends was studied in detail, and the adhesion characteristics of the blends were determined. Both the initial components and their blends are characterized by microphase segregation determining the set of the properties. The relationship between the rheology of blends and the character of the cleavage of the adhesive joints was demonstrated.
