Abstract: The invention relates to a transparent, stretchable film, especially for modified atmosphere food packaging, comprising at least three levels A,B,C and possibly D, wherein A is composed of a polymer P1 or a mixture of P1 and P2 and P1 is a rubber elastic block copolymer of styrene and a special softening phase of styrene and butadiene; the second layer B is made of a polymer P2 exhibiting a water vapour permeability Pw of less than 8; the third layer C is made of a polymer with an oxygen permeability Po of less than 1000; and optionally a fourth layer D made of a polymer without any limitation of permeability. The invention also relates to the use of the above-mentioned film as food packaging and to a method of packing food in particular, especially one using said film in a standard packing machine.

Abstract: A new catalyst (I) contains 0.01-30 wt% ruthenium or palladium as active metal, optionally together with Group I, VII or VIII transition metal(s), on a carrier (II) in which (novel feature) 10-50% of the pore volume consists of macropores with a pore diameter (PD) of 50-10,000 nm and 50-90% consists of mesopores with a PD of 2-50 nm. Also claimed are (i) a process for conversion of polymers containing multiple C-C bond(s) in presence of (I) and (ii) a process for conversion of organic compounds in the presence of (I) in which the active metal is ruthenium.

Abstract: A faint-smelling, light-, heat- and/or air-oxygen-stabilised moulding material made of at least one styrene homopolymer or copolymer or acrylate or methacrylate polymers contain stabilising amounts of for example 0.01 to 1 % by weight alpha-tocopherol and 0.1 to 2 % by weight of an organic phosphite, in a quantitative ratio between alpha-tocopherol and phosphite from 1:1 to 1:4, and preferably 0.01 to 2 % by weight of a sterically hindered phenol. The percentages by weight refer to the polymer fraction. The organic phosphite is in turn stabilised with up to 5 % by weight (in relation to the phosphite weight) of an amine or alkanolamine.
