Selectively transitioning polymerization processes |
abstract |
A method of selectively transitioning a polymerization process making an ethylene/alpha-olefin copolymer in such a way that melt elasticity of the copolymer is substantially changed without changing comonomer and without substantially changing density of the copolymer. A method of compensating a reactor temperature-induced change in melt elasticity with an inverse change in H2/C2 gas molar ratio. Also, use of process control variable(s) to selectively change the melt elasticity. |
