FIELD: chemistry.

SUBSTANCE: invention relates to N-substituted monomers and polymers, methods of producing such monomers and polymers and methods for their use for different medical purposes, e.g., in medical devices. Disclosed is a polymer which contains a repeating unit of formula (I), where X¹ and X² are independently selected from Br and I; y¹ and y² are equal to zero or an integer from 1 to 4, A¹ is selected from a group consisting of , , , and , R³ is selected from C₁-C₃₀ alkyl, and C₁-C₃₀ heteroalkyl, C₅-C₃₀ aryl, C₆-C₃₀ alkylaryl and C₂-C₃₀ heteroaryl; R⁴ is selected from H, C₁-C₃₀ alkyl and C₁-C₃₀ heteroalkyl; R¹ is (A) or (B); Z is O or S; R⁵ and R⁶ are selected from -CH=CH-, -CHJ¹-CHJ²- and -(CH₂)_a-; a equals zero or an integer from 1 to 8; J¹ and J² are independently selected from H, Br and I; Q is a group which contains 20 or more carbon atoms; R^x is selected from optionally substituted branched or straight C₇-C₃₀ alkyl and optionally substituted C₆-C₃₀ aryl; and R^y is selected from hydrogen, optionally substituted branched or straight C₁-C₃₀ alkyl and optionally substituted C₆-C₃₀ aryl. Also disclosed are versions of said polymer, methods of producing said polymers and a medical device containing the disclosed polymers. The medical device is preferably a stent.

EFFECT: disclosed polymer has improved physical and chemical properties and is suitable for use in implantable medical devices.
