  • Publication number: 20060167181
    Abstract: 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.

  • Publication number: 20060154098
    Abstract: A self-adhesive article made from a sheet or strip support at least partly coated on at least one side with a pressure-sensitive adhesive material based on polyacrylate, comprising at least one polyacrylate block copolymer with a sequence of hard polymer blocks [P(A)], having a glass transition temperature of not more than 10° C., preferably of 0 to ?80° C. and of soft polymer blocks [P(B)], having a glass transition temperature of more than 10° C., preferably 20 to 175° C. A microstructuring is thus generated, which permits the exchange of the smallest adhering and non-adhering regions and thus generates the desired easily stuck and easily removed adhesive action such as required for self-adhesive note pads.
