AbstractIn this paper a synthesis method for low molecular weight poly(orthoesters) with photo crosslinkable methacrylate endgroups is presented. Using this procedure, the molecular weight could be controlled and the desired endgroup functionality was introduced in a single reaction step. The detailed characterization of the molecular structure of bismethacrylate endcapped poly(ortho-esters) using NMR affords a re-evaluation of previous assignments reported for similar poly(ortho-ester) polymers. In addition, the use of diffusion filtered 1D 1H NMR spectroscopy as a simple but effective analysis tool that allows to distinguish resonance contributions from impurities and low molecular weight compounds, most probably the result of degradation, from those of the full size polymer, is demonstrated.
