Biocompatible, biodegradable surface-active polymers useful for preparing micellar systems or emulsions, stabilizing nanoparticles, encapsulating active substances and surface-treating biomaterials

摘要

New family of biocompatible surface-active copolymers that biodegrade by an erosion mechanism that does not change the degree of polymerization. Biocompatible surface-active polymers comprise at least one hydrophilic chain and at least one hydrophobic chain which is formed by a homopolymer consisting of repeat units of formula (I), a statistical copolymer comprising different units of formula (I) or a statistical copolymer comprising mostly units of formula (I). R1 = 1-6C alkyl or (CH2)mCOOR3; R2, R3 = 1-6C alkyl; m, n = 1-5.
