    摘要: Transparent acrylate pressure-sensitive adhesive comprising a filler, the acrylate-pressure sensitive adhesive comprising a polyacrylate and particles of silicate and/or of silica gel. The particles of silicate and/or of silica gel have a size of not more than 50 nm. The acrylate pressure-sensitive adhesive is prepared by a process in which acrylates and comonomers are polymerized in the presence of at least one organic solvent or in bulk, the particles of silicate and/or of silica gel being mixed in before or after the polymerization.

    摘要: The invention relates to a polyacrylate which as a result of a polymerization process has a broad, bimodal molecular weight distribution. These acrylate pressure-sensitive adhesives are preferably processed from the melt. The low molecular weight fraction lowers the flow viscosity, while the high molecular weight fraction results in the achievement of a high shear strength, following appropriate crosslinking, for the acrylate pressure-sensitive adhesive.
