N-SUBSTITUTED MONOMERS AND POLYMERS Russian patent published in 2012 - IPC C08G65/40 A61F2/82 A61L27/54 

FIELD: chemistry.

SUBSTANCE: invention relates to N-substituted monomers and polymers used in medical devices. Disclosed is a polymer meant for use in implantable medical devices, which contains a plurality of monomer repeating units containing an N-substituted amide of formula (I) where each of X¹ and X² is independently selected from Br and I; each y1 and y2 is independently equal to zero or an integer ranging from 1 to 4, and R¹ is selected from substituted or unsubstituted, saturated or unsaturated, straight or branched aliphatic groups containing up to 48 carbon atoms, substituted or unsubstituted aromatic groups containing up to 48 carbon atoms, and substituted or unsubstituted araliphatic groups containing up to 48 carbon atoms, wherein the aliphatic parts are straight or branched and saturated or unsaturated, wherein R¹ contains 2-8 heteroatoms selected from O, S and N, where two of the heteroatoms form an amide group of the polymer backbone chain which is an N-substituted C₁-C₆ alkyl group. Corresponding monomers and versions of use of the disclosed polymer in medicine are also disclosed.

EFFECT: disclosed polymers are characterised by low melt viscosity and can be easily processed without decomposition.
