Abstract: Processes are provided which include copolymerization using two different metallocene catalysts, one capable of producing high Mooney-viscosity polymers and one suitable for producing lower Mooney-viscosity polymers having at least a portion of vinyl terminations. The two catalysts may be used together in polymerization to produce copolymer compositions of particularly well-tuned properties. For instance, polymerizations are contemplated to produce high-Mooney metallocene polymers that exhibit excellent processability and elasticity, notwithstanding their high Mooney viscosity. Other polymerizations are also contemplated in which lower-Mooney metallocene polymers are produced, which also exhibit excellent processability and elasticity, while furthermore having excellent cure properties suitable in curable elastomer compound applications.

Abstract: Application relates to storage technologies, and in particular, to writing data in a storage system having solid state disks. Embodiments of the application provide an array controller, including a communication interface and a processor. The processor receives information about a logical block from a solid state disk. The information about the logical block includes a size of the logical block and indication information of the logical block, and the logical block includes one or more physical blocks. The processor sends multiple write data requests to the solid state disk. Each write data request includes data, and each write data request instructs the solid state disk to write the data into the logical block indicated by the indication information of the logical block. A total size of data included in the multiple write data requests is equivalent to the size of the logical block.
