COMPOSITIONS OF CRYSTALLINE PROPYLENE POLYMERS HAVING A LOW SEAL TEMPERATURE |
摘要 |
Discosed are compositions of crystalline propylene polymers comprising (by weight): A) 30-65% of a copolymer of propylene with a C4-C8 .alpha.-olefin, containing from 98 to 80% propylene; B) 35-70% of a copolymer of propylene with ethylene and optionally from 2 to 10% of a C4-C8 .alpha.-olefin, said copolymer containing 2 to 10% ethylene when the C4-C8 .alpha.- olefin is not present, and 0.5 to 5% ethylene when the C4-C8 .alpha.-olefin is present.
