Available to the general public. In a two-step polymerization reaction which involved prepolymer synthesis followed by chain elongation, a poly(ester-urethane) polymer was synthesized to meet the essential requirements of a biodegradable biomaterial. First, lauric acid was oxidized to hydroxylauric acid using the triflouroacetic acid-hydrogen peroxide reagent resulting to a mixture of monohydroxylauric acids with lactones as by products. The monohydroxylauric acid mixture and lactones were successfully characterized by GCFID and GC-MS. Polymerization. Sumera, Florentino C. adviser. FI UPD DARCHIVES LG 995 2013 C4 C37 Thesis
