    Abstract: A film in roll form, especially for packaging foodstuffs as a substitute for PVC film, of 15 to 99.6 wt% of a rubber-elastic styrene-butadiene block copolymer, 15 to 99.6 wt% of a thermoplastic polymer, 0.1 to 10 wt% of an anti-fogging agent, 0.1 to 5 wt% of a primary antioxidant, 0.1 to 5 wt% of a secondary antioxidant and 0.1 to 50 wt% of other auxiliaries. The transverse shrinkage of said film is not more than 3 % after three months' storage.

    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.

    Abstract: PCT No. PCT/EP95/02207 Sec. 371 Date Dec. 17, 1996 Sec. 102(e) Date Dec. 17, 1996 PCT Filed Jun. 8, 1995 PCT Pub. No. WO95/35335 PCT Pub. Date Dec. 28, 1995An elastomeric block copolymer comprising at least one block A having polymerized units of a vinylaromatic monomer and forming a rigid phase and at least one elastomeric block B/A having polymerized units of both vinylaromatic monomers and of a diene and forming a flexible phase, and glass transition temperature Tg of the block A being above 25 DEG C. and that of the block B/A being below 25 DEG C. and the phase volume ratio of block A to block B/A being chosen so that the amount of the rigid phase in the total block copolymer is 1 to 40% by volume and the amount of the diene is less than 50% by weight.
