Polyolefin compositions comprising: (A) 20 to 50 parts by weight of a particular propylene polymer having a MWD greater than 3.5; and (B) 50 to 80 parts by weight of an elastomeric ethylene copolymer having a low enthalpy of fusion and a narrow MWD. The compositions of the invention are capable of giving, after dynamic vulcanization, thermoplastic elastomeric products having optimum elastomeric properties and a good balance of physico-mechanical properties.

Dynamically vulcanizable polyolefin composition

The present invention relates to bituminous compositions, particularly suitable for paving and building waterproofing, comprising a bitumen and a copolymer of ethylene with propylene and/or other alpha-olefins and optionally with smaller proportion of a diene or polyene. The copolymer is besides characterized by a very low crystallinity, intrinsic viscosity higher than 1.5 dl/g and by a content of propylene units or of the alpha-olefin in form of triads comprised between 4 and 50% of the propylene or of the alpha-olefin, with at least 70% of said triads having isotactic structure.

Bituminous compositions modified with polyolefinic materials

The present invention relates to polyolefin compositions comprising: (a) 20 to 50 parts by weight of a particular propylene polymer having an MWD greater than 3.5; and (b) 50 to 80 parts by weight of an elastomeric ethylene copoymerR having a low enthalpy of fusion and a narrow MWD. The compositions of the invention are capable of gining, after dynamic vulcanization, thermoplastic elastomeric products having optimum elastomeric properties and a good balance of physico-mechanical properties

Dynamically vulcanizable polyolefin compositions

Shaped articles for biomedical use characterized by a good transparency and flexibility also at low temperatures are prepared starting from elastomeric copolymers of ethylene with propylene and/or other alpha-olefins having a unique set of mechanical properties and thermoplastic processability. Of particular interest are devices for containing, administering, draining and transport of blood and biological and physiological fluids, syringe seals and similar applications.

Shaped articles for biomedical use

This invention relates to plastoelastomeric polyolefinic compositions comprising an intimate mixture of the following components, in the indicated percentages by weight:
