  The multilayer structure is composed of a grafted high-density polyethylene resin layer directly attached to a resin layer of polyamide resin, polyester resin or a saponified copolymer of ethylene and vinyl acetate, or to a metal layer. In such structures it has been difficult to provide adequate bond strength between the iayers, and delamination has previously tended to occur under severe operating conditions. The grafted high-density polyethylene resin layer composed of (a) 97 to 50 parts by weight of a high-density polyethylene resin having a density of 0.945 to 0.970 g/cm3 and being grafted with an aliphatic dicarboxylic acid or functional derivative thereof, with or without a high-density polyethylene resin having a density of 0.945 to 0.970 g/cm3, (b) 3 to 50 parts by weight of an ethylene/4-methyl-1-pentene copolymer having an ethylene content of 93 to 99.5 moie% and a melt index at 190°C of 0.1 to 10 g/10 min., and (c) 0 to 20 parts by weight of a rubbery synthetic polymer or copolymer, the parts by weight of (a), (b) and (c) being per 100 parts by weight of resins (a) and (b) combined. The structures of the invention find use as, for example, packaging materials and building panels.

• Development of an organo- and enzyme-catalysed one-pot, sequential three-component reaction
  作者：Angela Kinnell、Thomas Harman、Matilda Bingham、Alan Berry、Adam Nelson

  DOI：10.1016/j.tet.2012.02.010

  日期：2012.9

  A one-pot, three-component process is described which involves both organo- and enzyme-catalysed carbon-carbon bond-forming steps. In the first step, an organocatalyst catalyses the aldol reaction between acetaldehyde and a glyoxylamide. After dilution with additional aqueous buffer, and addition of pyruvate and an aldolase enzyme variant, a second aldol reaction occurs to yield a final product. Crucially, it was possible to develop a reaction in which both the organo- and enzyme-catalysed reactions could be performed in the same aqueous buffer system. The reaction described is the first example of a one-pot, three-component reaction in which the two carbon-carbon bond-forming processes are catalysed using the combination of an organocatalyst and an enzyme.
