Synthetic thermoplastic rubber consisting of a mixture containing from 10% to 45% by weight of polypropylene, from 10% to 45% by weight of high-impact polystyrene and from 30% to 80% by weight of elastomeric copolymer of the linear type, of styrene/diene blocks whose diene is either butadiene or isoprene, having at least three polymeric sequences and a content in styrene lower than 50% by weight.

Thermoplastic rubber consisting of a mixture of polypropylene,

Thermoplastic material of high impact resistance, consisting of a homogeneous mixture of high-density polyethylene, high-impact polystyrene and of a styrene/diene block copolymer having a content in styrene below 50% by weight.

Polymeric material consisting of a mixture of high-impact polystyrene,

A polymer composition is disclosed which comprises polystyrene, polypropylene and a sequenced copolymer of conjugated diene and vinylaromatic compound such as styrene which has a radial structure. The polymer composition has improved migration properties.

Polymer compositions

Thermoplastic laminate suited for thermo-forming, consisting of at least one sheet of crystalline polypropylene and of at least one sheet of polymeric material consisting of a mixture of high-impact polystyrene (from 1% to 75% by weight), crystalline polypropylene (from 20% to 85% by weight) and of styrene/dienic monomer block copolymer with three or more sequences (from 5% to 15% by weight).
