obtain photopolymerizable PBAEs end-capped with acrylate groups on

both ends (see Fig. 6.12). A large combinatorial library of liquid PBAEs

( M = 2000–3000 Da) was synthesized by Anderson et al . with various deg-

radation pro les and elastic moduli (4–350 MPa) (Anderson et al ., 2006). In

the following paper, the most promising candidate in terms of mechanical

properties, degradation, cell viability, and osteoconductivity has been iden-

ti ed to be PBAE made of isobutylamine and diethylene glycol diacrylate

(Brey et al ., 2010). Mild in ammatory reaction was observed if scaffold was ...
