摘要:
The present invention relates to a novel production method of 4,6-diaminoresorcin, and to 2-sulfonic acid-4,6-dinitroresorcin as its intermediate and salts thereof. The target compound is obtained by (R1) sulfonating resorcin (A) to obtain resorcin 2,4,6-trisulfonate (B), (R2) nitrating the compound (B) to obtain 2-sulfonic acid-4,6-dinitroresorcin (C), (R3) hydrolyzing the compound (C) to obtain 4,6-dinitroresorcin (D), and finally (R4) reducing the compound (D) to obtain 4,6-diaminoresorcin (E):

摘要:
A thermoplastic polymer compound can be obtained by allowing a compound having a bivalent organic group to react with a polyoxyalkylene diol obtained by addition-polymerization of an urea compound having a partial structure refractivity of 14 to 35 and a dipole moment of 2.5 D to 5.5 D with an alkylene oxide. A thermoplastic polymer composition comprises the thermoplastic polymer compound and an inorganic salt of an alkali metal or the like. The polymer compound and the polymer composition are useful as an antistatic agent and have excellent antistatic properties and excellent transparency.
