There is provided a process for the copolymerisation of propylene with at least one C4-20 \u03b1-olefin or C4-20 diene in a reaction medium in the presence of a catalyst system at a temperature of greater that 80\xb0 C. The VWSMs include a first VWSM that is coupled to a first access port via the first wired Ethernet interface that is allocated to the first VWSM, and a second VWSM that is coupled to a second access port via the second wired Ethernet interface that is allocated to the second VWSM. The pair of curved arms are respectively formed with upper and lower contact portions. In some embodiments, the core may include a core assembly including a core body, an Achilles sheave coupled with the core body and a toe bracket coupled with the core body. Similarly, the third curved arm has a top contacting end for contacting with the CPU. The adsorbents of the present invention and the method of producing such adsorbents maximize the working adsorption capacity through \u03c0-complexation.
