  • Adhesives for frozen substrates
    Patent number: 6833041
    Abstract: The use of free-radically polymerized, UV-crosslinkable polymers which consist to the extent of at least 50% by weight of C2 to C18alkyl(meth)acrylates as adhesives for the bonding of carriers coated with the polymer on substrates, wherein from 0.1 to 30% by weight of the monomers of which said polymer is composed are monomers A without carboxylic acid or carboxylic anhydride groups and with a water solubility of more than 5 g of monomers per liter of water and said substrates are moist substrates, especially refrigerated substrates.

  • Adhesives containing polyvinyl alkyl ethers
    Patent number: 6734222
    Abstract: The invention relates to a mixture, containing A) a polymer, which consists to an extent of at least 40 wt % of C1-C18 alkyl (meth)acrylates (referred to herein as polyacrylates) and B) a homopolymer or copolymer of vinyl alkyl ether (referred to herein as polyvinyl alkyl ether), which consists, to an extent of at least 70 wt %, of structural units of the following formula, in which X stands for a single bond or a C1-C3 alkyl group and R for a C1-C6 alkyl group.
