POLYESTER POLYMERS FUNCTIONALIZED WITH CARBOXYLIC ACID OR SALT OF ACID Russian patent published in 2017 - IPC C08G63/12 C08G63/127 G03G9/87 

FIELD: chemistry.

SUBSTANCE: described ester polymer, which is a chain of 25 repeat units, comprising at least two adjacent residues containing side chain, which is a carboxylic acid group or a side chain which is a salt of a carboxylic acid, characterized by the following structures 12[N]-2[F]_M-11[N], [F]_T-[F]_M-23[N], 23[N]-[F]_M-[F]_H, 11[N]-3[F]_M-11[N], where [F]_M represents a functionalised polymer as a repeating unit within the polymer chain dimer, [F]_T It represents functionalized polymer repeating unit in the form of dimer or tail position at the end of the polymer chain, [F]_H It represents functionalized polymer repeating unit in the form of a dimer in the head position or at the end of the polymer chain. Where [N] represents [F] represents where R=CH₂CH₂. Wherein the ester polymer characterized in that the temperature is lowered to a temperature near the glass transition temperature it self assembles into micelles having a diameter of about 38 at 330 K. E also discloses a toner particle comprising a polymer above. The developer is disclosed comprising a toner particle mentioned above.

EFFECT: obtaining polyester forming self-assembling units, used in the manufacture of toner for use in imaging systems.
