PROCESS OF PREPARING CATIONIC LATEX WITH HOLLOW POLYMERIC PARTICLES Russian patent published in 2006 - IPC C08F2/22 C08F265/04 C08F6/14 C08F291/00 

FIELD: polymer materials.

SUBSTANCE: invention relates to preparing aqueous cationic latexes with hollow polymeric particles serving as multifunctional additives used when preparing polymer compositions, paintwork materials, coatings (including paper coatings), and in other applications as white pigment and filler reducing density of material and internal stresses arising during formation of coatings or polymer materials. Process comprises at least three following stages: (A) preparing functional core copolymer, (B) preparing particles with core-shell morphology, and (C) ionization of functional groups of core copolymer. All process stages are carried out as a series of consecutive transformations in the same reactor without discharge of intermediate products. As monomer containing functional groups in stage A, vinylbenzyl chloride is used, and stage C represents amination of vinylbenzyl chloride units with tertiary aliphatic amines, pyridine, or derivatives of the latter.

EFFECT: improved and simplified technology and improved characteristics of cationic latex.
