A representative example is the synthesis of amino acid based polyurethanes using L-tyrosine based chain extender, PEG and polycaprolactone diol as soft segments, and HDI and HMDI as diisocyanate components [38, 39]. By altering the soft and diisocyanate components, the researchers were able to prepare a number of polyurethanes with varying hydrophobicities and degradation behavior.
