Use of phosphoric esters as deposit control agents during the synthesis, purification or regeneration of (meth)acrylic monomers

摘要: The compounds of formula (I) are suggested for use as deposit control agents preventing the polymeric or resulting in addition reactions on (meth)acrylic double bonds during synthesis, purification, regeneration monomers operations. R1 represents a C3-C30 alkyl radical, an aryl radical alkylaryl these radicals being able to be interrupted bound oxygen molecule by chain -(OR4)o- R4's, independent one another, represent ethylene, propylene butylene and, o is integer from 1 50; R2 R1, hydrogen atom counterion, and; R3 counterion.
