Abstract

The pressure-sensitive adhesive properties of miscible blends of poly(vinylethylene- co-1,4-butadiene) (V-BR) with terpene resins were investigated on varying both the random copolymer composition (vinyl content) and the blend composition. The V-BR with 47.4 wt% vinyl content was found to be a remarkable rubber for use as a base polymer for a blend adhesive. In V-BR(47.4)/terpene resin blends, excellent pressure-sensitive adhesive properties were revealed for 50 50 blends. The good results for the adhesive properties were interpreted in terms of the dynamic mechanical behaviour of the blends.
