Novel carbamate antistatic agents
Abstract
Abstract NEW COMPOUNDS WITH ANTISTATIC PROPERTIES ARE PROVIDED. THE NEW COMPOUNDS ARE CARBAMATES AND QUATERNARY DERIVATIVES THREOF, WHICH IN THEIR BASE FORM ARE REPRESENTED BY THE FORMULA I: R4-(R5-)N-(1,4-PHENYLENE-O)M-(CH2-CH(-X)-O)N-CO-NH-(CH2)3N(-R1)-R2 WHEREIN R4 AND R5 ARE ALKYLF X IS HYDROGEN, METHYL OR ETHYL; R1 AND R2 ARE INDIVIDUALLY ALKYL OR HYDROXYALKYL: N IS AN INTEGER OF FROM 1-10; AND M IS 0 TO 1. THE QUATERNARY COMPOUNDS ARE THE HYDROXYALKYLAMMONIUM DERIVATIVES SUCH AS THOSE OBTAINED BY HEATING THE COMPOUNDS OF FORMULA I WITH AN ALKYLENE OXIDE IN THE PRESENCE OF AN ACID. TYPICALLY, THE COMPOUNDS OF THE INVENTION ARE APPLIED BY DIPPING AN ARTICLE, SUCH AS A FIBER, INTO A SOLUTION OF THE CARBAMATE IN A SUITABLE SOLVENT. REPRESENTATIVE ANTISTATIC AGENTS OF THE PRESENT INVENTION ARE PREPARED BY THE REACTION OF PHOSGENE WITH AN ETHOXYLATED DIALKYLAMINE, GIVING A CHLORCARBONATE WHICH IS THEN REACTED WITH N,N-DIMETHYLPROPYLENEDIAMINE IN SUFFICIENT QUANTITIES TO FULLY REPLACE ALL THE CHLORINE.
