Photo-crosslinking copolymers based polyanhydride and 1G polyamidoamine-methacrylamide as bone tissue engineering: Synthesis, characterization, and in vitro degradation 
(1961-1968) Polymer Degradation and Stability 95 #10 (2010)
Shi et al found that copolymer with 50–60 wt% polyamidoamine-double bond show more excellent mechanical properties compared with other formulations.  Copolymers degraded mainly by surface erosion but the bulk erosion pattern also appeared at the initial time of degradation for formulation 30% and 40%. The material was expected to be useful for drug controlled delivery, tissue engineering scaffold and other biomedical applications.  (RDC 12/10/2010)
