    摘要： The embodiment relates to a printed circuit board. The printed circuit board includes an insulating substrate having a plurality of circuit pattern grooves, a conductive absorption layer including conductive particles absorbed into inner walls of the circuit pattern grooves and circuit patterns formed on the conductive absorption layer such that the circuit pattern grooves are filled with the circuit patterns. Since the electroplating process is selectively performed with respect to inner portions of the pattern grooves by using the conductive absorption layer as a seed layer, the plating layer is not formed on the insulating layer except for the pattern grooves, so that the etching process for the electroplating layer is not necessary and the patterns are stably formed.

    摘要： This invention relates to a process for polymerizing isobutene using a catalytic system comprising a transition metal compound, a benzene derivative compound, and methylaluminoxane, and the catalytic system applied to the polymerization of isobutene, (1) the added benzene derivative compound and methyl aluminoxane to the transition metal species provides higher stability of cation active site so that polyisobutene with a high molecular weight can be produced even at a higher reaction temperature than the conventional cationic polymerization temperature; (2) nonhalogen solvent such as toluene can be employed as a polymerization solvent instead of halogenated solvents such as methyl chloride; and (3) under the stable catalytic system, a final product with a high yield can be ensured for its long-term use.
