摘要： The present embodiments provide a system and method for separation within a polymer production process. Specifically, a flashline heater configured according to present embodiments may provide more time than is required for complete vaporization of liquid hydrocarbons that are not entrained within a polymer fluff produced within a polymerization reactor. Such extra time may allow for liquid hydrocarbons that are entrained within the polymer fluff to be vaporized.

摘要： Disclosed are an apparatus and a method for removing halogens generated during the preparation of polybutene, which are capable of improving the utilization of polybutene and light polymers by removing halogen components contained in the polybutene and the light polymers. The method for removing halogens generated during the preparation of polybutene comprises the steps of: preparing a reaction product by supplying a catalyst and a reaction raw material to a reactor and polymerizing; removing a catalyst component from the reaction product and neutralizing; separating the reaction product into an organic compound and impurities comprising the catalyst component; heating the organic compound to distill an unreacted material; and removing a halogen component in a remaining polymerization mixture after the distillation using a halogen removing catalyst, or removing a halogen component in polybutene and light polymers obtained from the polymerization mixture using the halogen removing catalyst.

摘要： The present invention relates to a microporous polyethylene film for use as battery separator. The microporous polyethylene film according to the present invention is characterized by having a film thickness of 5-40 μm, a porosity of 35-55%, a permeability from 2.5×10−5 to 10.0 10−5 Darcy, a puncture strength of at least 0.10 N/μm at 90° C., a puncture angle of at least 30° at 90° C., and a permeability from 2.0 10−5 to 8.0 10−5 Darcy after shrinking freely at 120° C. for 1 hour. The microporous polyethylene film in accordance with the present invention has very superior puncture strength and thermal stability at high temperature and takes place of less decrease of permeability due to low thermal shrinkage at high temperature, as well as superior permeability. Therefore, it can be usefully applied in a high-capacity, high-power battery to improve thermal stability and long-term stability of the battery.
