PLASTO-ELASTIC POLYPROPYLENE COMPOSITIONS |
摘要 |
Polypropylene compositions having valued plasto-elastic properties, in the form of spheroidal flowable particles with an average diameter included between 500 and 7000 um having the following composition: A) 10-60 parts by weight of homopolymer polypropylene with isotactic index greater than 90, or of crystalline propylene copolymer writh ethylene and/or an alpha olefin such as butane-1, pentene 1 or 4-methyl-1-pentane, containing over 85% by weight of propylene and having an isotactic index greater than 85; B) 10-40 parts by weight of a polymer fraction containing ethylene, insoluble in xylene at roars temperature; C) 30-60 darts by weight of an amorphous copolymer ethylene- propylene fraction optionally containing small proportions of a diene, soluble in xylene at room temperature and containing 40-70% by weight of ethylene. |
