products and possess degradation speed similar to polyacrylates. Poly(vinyl
ester)s degrade much faster, due to less sterical hindrance. On the other
hand, poly(vinyl carbamate)s are nearly non-degradable.
Finally, 3D cellular scaffolds made of trimer fatty acid trivinyl ester
(FTV)/divinyl adipate (DVA), as well as from poly(hexamethylene carbon-
ate) divinyl carbonate (HVC)/ethylene glycol divinyl carbonate (4VC) (see
Fig. 6.17), were fabricated by SLA and DLP respectively. In vivo tests of
implanted scaffolds into surgical defects of the distal femoral bone of adult
New Zealand White rabbits showed ...
