The types of packages and containers in circulation are extremely wide-ranging: glass bottles, aluminum cans, detergent containers, gift-wraps, food packaging films and so forth. According to the statistics for 2007, total expenditure on packages and containers reached 6.2 trillion yen 1). The theme of this article, extrusion lamination processing, plays an important role in manufacturing paper...

Vinylether monomers offer unique properties for UV/EB curing due to their efficiency as reactive diluents and their ability to undergo both cationic homopolymerization and free-radical copolymerization. The benefits derived from the inclusion of vinylethers into commercial UVcurable epoxysilicone formulations include viscosity reduction, improved cationic photoinitiator miscibility, and lower c...

The reaction of a tannin extract (containing about 30"/0 carbohydrate) from loblolly pine (Pinus taeda L.) bark (two parts) and resorcinol (one part) at 12O"C for 24 h with acetic acid catalyst gave a product containing predominantly oligomeric procyanidin-4-resorcinol adducts (3Wo), unreacted resorcinol (22%). carbohydrate (20010). the resorcinol adduct 2R,3R,4S 4-(2.4-dihydroxyphenyl).fIavan-...

We use the automorphism group Aut(H), of holes in the lattice L8 = A2 ⊕ A2 ⊕ D4, as the starting point in the construction of sphere packings in 10 and 12 dimensions. A second lattice, L4 = A2 ⊕ A2, enters the construction because a subgroup of Aut(L4) is isomorphic to Aut(H). The lattices L8 and L4, when glued together through this relationship, provide an alternative construction of the lamin...

Introduction The tremendous growth of activity in the composites industry continues to create a need for materials that meet the tough demands for environmental compliance and high performance at an economical cost. Much of this activity has been focused on composite systems based on unsaturated polyester resins (UPRs) and vinyl esters (VEs) utilized in laminating, gel coat and free-flowing mol...

Black pine (Pinus nigra) has high industrial usage potential and large plantation in Turkey. Larch wood was treated with heat to determine its mechanical properties, such as bending strength and pressure and order to determine its adhesion strength. Laminating adhesives are used for the construction of polyvinyl acetate and polyurethane. Heat treatment was applied to the samples at 100-150°C fo...
