METHOD OF MANUFACTURING MONODISPERSE POLY(METH) ACRYLATE PARTICLES

摘要

The invention relates to a method of manufacturing monodisperse poly(meth)acrylates by the method of precipitation polymerization, comprising polymerizing i) a monomer mixture comprising at least 60 wt.% of monomer of formula I (see fig.I) where R represents hydrogen or methyl; and R1 represents a C1-8 alkyl group, a C6-24 aryl group, a C1-8 alkyl substituted aryl group or an aralkyl group; ii) 0.1-10 wt.% based on the weight of the monomer mixture of a block copolymer having polystyrene components; and iii) 0.02-2 wt.% based on the weight of the monomer mixture of a percarbonic acid ester; in a halogen free solvent comprising 70 to 100 wt.% of cyclohexane.
