20110226416 | POLYMER FILM WITH MULTIPHASE FILM MORPHOLOGY - Described is a polymer film with multiphase film morphology. The polymer film, within a layer, has regions of a first polymer and regions of a second polymer, and is prepared from an aqueous polymer dispersion, comprising the two polymers in dispersed form and a tackifier. The glass transition temperature of the second polymer is greater than that of the first polymer and less than 20° C. The concentration of the tackifier in the polymer film is greater in the regions of the first polymer than in the regions of the second polymer. Described also are polymer dispersions for producing polymer films with multiphase film morphology, and also applications as adhesive, coating or sealant, as for example for producing self-adhesive paper labels. | 09-22-2011 |
20120077030 | MULTISTAGE PREPARATION OF AQUEOUS PRESSURE-SENSITIVE ADHESIVE DISPERSIONS FOR PRODUCING SELF-ADHESIVE ARTICLES - Described is a process for preparing an aqueous pressure-sensitive adhesive dispersion from ethylenically unsaturated, free-radically polymerizable monomers. In a first stage, a first polymer is prepared by free-radical emulsion polymerization. In a second stage, an aqueous polymer dispersion is prepared in the presence of the first polymer, where the glass transition temperature calculated for a polymer prepared from the monomers of the second stage is less than −20° C. The monomers of the first stage comprise monomers with acid groups. The polymerization of the first stage takes place at a low pH of less than 5. The acid groups of the first polymer are neutralized during, or before and during, the polymerization of the second stage to an extent such that the pH of the polymer dispersion at the end of the second stage is greater than 5. The aqueous pressure-sensitive adhesive dispersions can be used for producing self-adhesive articles, especially self-adhesive labels and adhesive tapes. | 03-29-2012 |
20120213992 | PSA POLYMER OF N-BUTYL ACRYLATE, ETHYL ACRYLATE, VINYL ACETATE, AND ACID MONOMER - Described is a pressure-sensitive adhesive (PSA) polymer formed from (i) 50%-95% by weight of n-butyl acrylate, (ii) 1%-20% by weight of ethyl acrylate, (iii) 1%-20% by weight of vinyl acetate, (iv) 0.1%-5% by weight of at least one ethylenically unsaturated acid or ethylenically unsaturated acid anhydride, and (v) 0% to 30% by weight of other ethylenically unsaturated compounds different from the monomers (i) to (iv). The PSA polymer can be used for producing self-adhesive articles, more particularly paper labels or film labels. | 08-23-2012 |
