Various other PEA polymers have been examined for biological degradation,

including several that are commercially available.11 Ongoing research interest focuses

on the suitability of the PEA polymers for various applications including; substitutes for

traditional condensation polymers (nylons and polyesters),9'10 drug delivery systems,1

micro-spheres,18 and biosensors.19,20 The successful polymerization of these monomers

with 2nd generation Grubbs' catalyst eliminated a problem encountered in earlier research

in this area. The amino alcohol polymers described herein are shown to be enzymatically

degradable. They are also the first such polymers made through ADMET

polymerization.
