A copolymer expressed by the following structural formula 1was obtained by loading adamantyl methacrylate monomer and t-butyl acrylate monomer by 1:1, then conducting polymerization, adding AIBN as a polymerization initiator, and then conducting precipitation purification with methanol. Each processing unit and each board include a first communication port, the first communication ports of the first unit and of the first board, and, respectively, of the second unit and of the second board, being interconnected by a wired communication link. As a result, other cables coupled to adjacent connectors will always maintain good connection during the plugging or unplugging process. With the measured impedance, impedance matching can be accomplished. The methods use low shear devices, and thus the temperature of the emulsions is kept low, while enhanced particle size and viscosity are obtained.
