Patent number: 6265529Abstract: Disclosed is an antistatic monomer-cast nylon (MC nylon) polymer. The MC nylon polymer includes graphite particles nonuniformly distributed in an MC nylon polymer structure. The graphite particles are partially agglomerated and form a micro-domain phase. The antistatic MC nylon has volume specific resistance of about 105 &OHgr;·cm to about 109&OHgr;·cm. Also disclosed is a method of producing antistatic MC nylon. A mixture comprising a monomer of the nylon and graphite is prepared and cast in a mold. The mixture is stirred to disperse the graphite and the monomer polymerizes to form an antistatic MC polymer.Type: GrantFiled: November 12, 1999Date of Patent: July 24, 2001Assignee: Polypenco Korea Company LimitedInventors: Dae-won Chung, Chang-Hoon Kim

Patent number: 5367094Abstract: This invention pertains to an improved process for preparing chiral or racemic phenylalaninol (PAO) by hydrogenation of L(+)- or racemic 2-amino-1-phenyl-1,3-propanediol (APPD) in the presence of a strong volatile acid. Furthermore, a more valuable form of PAO such like N-blocked PAO was found to be directly produceable from the hydrogenation mixture without isolation of PAO, when a volatile acid was used as the medium of the hydrogenation reaction.Type: GrantFiled: June 4, 1993Date of Patent: November 22, 1994Assignee: Yukong, Ltd.Inventor: Dae-won Chung
