Polypropylene copolymer composition with sub-zero impact resistance |
| abstract |
A polypropylene polymer composition that can be formulated to have excellent clarity properties along with excellent impact resistance properties at sub-zero temperatures is disclosed. The polypropylene polymer composition is a heterophasic composition containing a first phase polymer in combination with a second phase polymer. The first phase polymer is a polypropylene and alpha-olefin copolymer, while the second phase polymer is also a polypropylene and alpha-olefin random copolymer. The second phase polymer contains a relatively high amount of ethylene. It has been found that increased amounts of ethylene in the second phase polymer dramatically improve impact resistance at sub-zero temperatures. |
