CRYSTALLINE PROPYLENE COPOLYMER COMPOSITIONS HAVING IMPROVED SEALABILITY AND OPTICAL PROPERTIES AND REDUCED SOLUBILITY |
摘要 |
Propylene polymer compositions comprising (by weight): A) from 15% to 60% with C4-C8 alpha-olefin(s), containing more than 10%, but less than 14%, of said C4-C8 alpha-olefins (s); B) from 40% to 85% of a copolymer of propylene with C4-C8 alpha-olefin(s), preferably butene, containing from 14% to 30% of said C4-C8 alpha-olefin(s), and optionally from 0.5% to 3% of ethylene; provided that the total content of C4-C8 alpha-olefin(s) in the propylene polymer composition be higher than 10%. |
