High melt strength polymers and method of making same |
| 摘要 |
A polymer composition that has a backbone chain; and a plurality of long chain branches connected to the backbone is described. The polymer composition also has a value of <SUP>2</SUP>g'<SUB>LCB</SUB>-<SUP>1</SUP>g'<SUB>LCB </SUB>that is less than about 0.22, where <SUP>1</SUP>g'<SUB>LCB </SUB>is the long chain branching index for a fraction of the composition having a M<SUB>w </SUB>of 100,000 and <SUP>2</SUP>g'<SUB>LCB </SUB>is the long chain branching index for a fraction of the composition having a M<SUB>w </SUB>of 500,000.
