Title:
INHIBITION OF POLYMERIZATION OF BASIC ACRYLIC MONOMER
Document Type and Number:
Japanese Patent JPS6259607
Kind Code:
A
Abstract:
PURPOSE: To prevent polymerization of a basic acrylic monomer markedly even at a high temperature and to make the economical production of this monomer possible, by adding a specified substituted anthraquinonesulfonic acid to the monomer.
CONSTITUTION: To a basic acrylic monomer of the formula (wherein R is H or CH3, X is O or NH, A is a 1W3 C alkylene and R1W2 are each H or a 1W4 C alkyl), 0.01W2.0wt% at least one substituted quinone selected from among sodium anthraquinone-2-sulfonate, sodium anthraquinone-2,6-disulfonate and sodium anthraquinone-2,7-disulfonate is added.
