IMPACT COPOLYMER COMPOSITIONS FOR USE IN CORRUGATED BOARD |
摘要 |
<p>The present invention relates to polymer compositions comprising a propylene impact copolymer and a processing aid, as well as corrugated boards made from such compositions. The impact copolymer has a melt flow range of from 1.5 to 3.5 g/10 min and a dispersed phase content of from 5 to 30% by weight. The dispersed phase of the impact copolymer has an ethylene content of from 30-to 70% by weight of the dispersed phase. The matrix phase of the impact copolymer is a propylene homopolymer or a random copolymer comprising units derived from propylene and a second copolymer selected from either ethylene or 1-butene wherein the units derived from the second copolymer comprise from 0 to 5% by weight of the dispersed phase.</p> |
