POLYMERS OBTAINED VIA POLYMERISATION UNDER EFFECT OF NITROXY RADICALS Russian patent published in 2011 - IPC C08F2/38 C08F293/00 C08F220/06 C08F220/22 C08F220/32 C08F220/38 C08F220/40 C08F220/56 C08F20/10 B01F17/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a polymer of formula (I): In-[(A)_x-(B)_y-( A')_x-(E)_z]_n, obtained via controlled free-radical polymerisation using nitroxyl radicals with excess acrylate. In is a fragment of an initiator. A and A' are identical or different monomers selected from a group comprising methylacrylate, ethylacrylate, ethylhexylacrylate, propylacrylate, cyclohexylacrylate, hydroxyethylacrylate, n-butylacrylate, styrene and vinylpyridine. The amount of unsubstituted C₁-C₂₂ alkyl acrylic esters and/or C₁-C₂₂ alkyl methacrylic esters is more than 30 wt %. B is propargylacrylate. E is a group containing at least one stable nitroxyl free radical.

EFFECT: obtaining polymers suitable for use as a wetting or dispersing agent for dyes, as well as starting material for all reactions starting with alkyne or for hydrosilylation reactions.
