20120129975 | STYRENE-BUTADIENE COPOLYMERS, PROCESS FOR THE PREPARATION THEREOF AND HIGH COHESION ADHESIVE COMPOSITIONS - The present invention relates 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. | 05-24-2012 |
20130172445 | WATER-BASED RESIN COMPOSITION AND ARTICLES MADE THEREFROM - An aqueous elastomer dispersion includes a dispersed phase and an aqueous phase. The dispersed phase includes an elastomer including curable aliphatic conjugated-diene elastomers, such as polyisoprene, and a minor amount of at least one additive. The aqueous phase includes water and other optional components in either a soluble state or a dispersion state. The aqueous elastomer dispersion may be prepared by dissolving an elastomer, such as rubber, and additives in a solvent mixture and then converting the resulting solution into an aqueous emulsion. The aqueous emulsion is concentrated and the solvent is stripped from it to yield a dilute latex. The dilute latex that is obtained is concentrated again. Articles made from the aqueous elastomer dispersion include medical gloves, condoms, probe covers, dental dams, finger cots, catheters and the like. | 07-04-2013 |
