Claims18
A composition comprising:
- (a) an acrylated or methacrylated citric-acid-based polymer;
- (b) a photoinitiator compound, wherein exposure to light of an appropriate wavelength results in formation of a first reactive species from the photoinitiator compound;
- (c) a thermal initiator compound, wherein exposure to heat results in in formation of a second reactive species from the thermal initiator compound;
- (d) a poly(L) lactic acid (PLLA);
- and
- (e) a contrast agent, wherein the contrast agent is radiocontrast agent.
