Abrégé
(EN)
FIELD: organic chemistry. SUBSTANCE: non-crosslinked non-polypeptide polymers containing biogradable lypophilic side chains containing methylene diester fragments of formula (I): CO-O-C(R1R2)-O-CO, (1) wherein R1 and R2 each is hydrogen atom or monovalent organic group attached to carbon or R1 and R2 together form divalent organic group attached to carbon due to which fact lypophilic fragments are biogradable cleavably and form water- soluble polymer. EFFECT: improved properties of the non- crosslinked non-polypeptide polymers.

(RU)
Несшитые неполипептидные полимеры, содержащие биоразлагаемые липофильные боковые цепи, содержащие метиленовые диэфирные фрагменты формулы, приведенной в описании. Липофильные фрагменты являются биоразлагаемо отщепляемыми с образованием растворимого в воде полимера.
