  • Photo-curable polymer composition and flexographic printing plates containing the same
    Patent number: 6506541
    Abstract: The present invention relates to a photo-curable polymer composition comprising: a) a first block copolymer comprising at least two blocks A of polymerised mono-vinyl aromatic monomer, and at least one block B of polymerised conjugated diene monomer, wherein the total polymerised mono-vinyl aromatic monomer content is in the range from 5 to 25% by weight of the block copolymer; b) 5 to 10% by weight of a second block copolymer having one block A of polymerised mono-vinyl aromatic monomer and at least one block B of polymerised conjugated diene monomer, wherein the total polymerised mono-vinyl aromatic monomer content is in the range from 5 to 50% by weight of the block copolymer, alkoxy or epoxy functional groups; and c) at least 5% by weight of a low molecular weight block copolymer, wherein the total of (b) and (c) is from 15% by weight to 80% by weight, the low molecular weight block copolymer having one block A of polymerised mono-vinyl aromatic monomer, and at least one block B of polymerised conjugated

  • Polybutene/liquid polydiene hot melt adhesive
    Patent number: 6211272
    Abstract: It has been surprisingly found that certain properties including adhesion strength to smooth surfaces may be improved by making hot melt adhesives from blends comprising a poly-1-butene polymer, a tackifier resin, and from 3 wt. % to 25 wt. % of a liquid or semi-liquid, hydrogenated or partially hydrogenated low molecular weight conjugated diene polymer prepared by anionic polymerization.

  • Low VOC, high solids fumigation adhesive composition
    Patent number: 5932648
    Abstract: A low viscosity, low VOC content fumigation adhesive formulation which is comprised ofa) 100 parts by weight (pbw) of a blend of a styrene-diene triblock copolymer, hydrogenated or unhydrogenated, having a weight average molecular weight of 30,000 to 200,000 and a polystyrene content of from 10 to 40% by weight of the polymer, and a styrene-diene diblock copolymer having a weight average molecular weight of 10,000 to 40,000 and a polystyrene content of from 10 to 40% by weight of the polymer, wherein the diblock comprises from 60 to 95% by weight of the polymer blend,b) 75 to 275 parts by weight (pbw) of a tackifying resin which is compatible with the diene blocks, andc) 50 to 200 parts by weight (pbw) of a solvent for the polymer.
