## Abstract In the present work, a series of aromatic/aliphatic co‐polyureas have been synthesized from 4,4‐diphenylmethane diisocyanate (MDI), __m__‐phenylene diamine (__m__‐PDA), and 1,6‐diaminohexane (HDA) in DMAc by a two‐stage solution polymerization route. Characterizations of the polyurea pr
Monomers with Ieucine-tyrosine linkages were synthesized using diphenyl phosphoryl azide asa coupling reagent. Leucyltyrosylpoly (propylene glycol) bis(2-aminopropy lether) tyrosylleucine (monomer 1) hasalonger spacer: poly(propylene glycol) bis(2-aminopropy lether (,Jeffamine@ D-400), and leucyltyr
