Thermoplastische Polymermassen

摘要

Compositions comprise 10 to 90 weight per cent of a high isotactic content polypropylene resin having a melt index at 230 DEG C. of 0.1 to 5.0 and 10 to 90 weight per cent of a crystalline ethylene/butene-1 copolymer resin containing 1 to 30 weight per cent of ethylene and having a polybutene type crystal lattice. The compositions may be extruded to form biaxially oriented, shrinkable films.
