EPOXY-TERMINATED POLYESTER Russian patent published in 2019 - IPC C08G59/12 C08G59/50 

FIELD: chemistry.

SUBSTANCE: invention relates to epoxy-terminated compounds. Disclosed is an epoxy-terminated polyester, having structure (I), where R¹ corresponds to structure (II), G corresponds to formula (III), j ranges from 1 to 5, R² corresponds to formula (IV), where R⁴ and R⁵ all independently represent a divalent organic group, p is 0–20, where R³ denotes -(CH₂)_q- or (V), where q ranges from 1 to 8, R²¹ and R²² denote independently a divalent alkyl group that contains 5 or fewer carbon atoms.

(IV),

(V).

EFFECT: disclosed epoxy-terminated polyesters have the required low viscosity in the temperature range of 25–70 °C.
