and the properties of the polymer solution can be estimated based on the osmotic pressure calculation formula of a reliable solution. The Flory-Huggins theory is used to describe the behavior of polymer solutions, calculating osmotic pressure as a function of the molecular weight of polymers by con...
摘要: PROBLEM TO BE SOLVED: To efficiently control the molecular weight of an olefinic polymer with a reduced amount of hydrogen by feeding a mixed gas of hydrogen and an inert gas to the polymerizer, when olefin is polymerized or copolymerized by using a metallocene catalyst....
