    摘要: The present patent of invention application refers to styrene-butadiene copolymers (SBR) that are prepared using aqueous emulsion polymerization technology and are intended for the adhesive and sealing industry, being particularly useful in the preparation of contact adhesives and pressure-sensitive adhesives (PSA) and widely applicable in the footwear and furniture industries. The use of this kind of elastomer in processes for preparing adhesives, having an aqueous or solvent base, provides high cohesion to adhesive compositions without compromising or jeopardizing the adhesion. The present invention is also intended to protect the process for obtaining SBR copolymers, simultaneously comprising: aqueous emulsion polymerization at high temperatures, the use of a specific surfactant and the maintenance of the Mooney viscosity and the combined styrene content in the copolymer in high ranges. Another object of the present invention application is the protection of adhesive compositions that are obtained from SBR copolymers, either in solid or latex form.
