A series of “N-terminus” amino acid and peptide branched, chiral polyolefins, termed bio- olefins, have been prepared using acyclic diene metathesis (ADMET) polycondensation chemistry, using a minimal amount of solvent and Grubbs' second generation catalyst. The carboxylic acid functional groups were protected with methyl, benzyl, and tert-butyl esters to enhance both the polymerizability of the monomers themselves and the solubility of the ...
