Hydrolytic degradation of the biocomposites is rendered by a degradable macromer / crosslinker , dimethacrylated poly ( lactide - b - ethylene glycol - b - lactide ) , which first degrades to break up 3 - D hydrogel networks , followed by dissolution of linear pHEMA macromolecules and bioceramic particles .
 Chemical: dimethacrylated poly ( lactide - b - ethylene glycol - b - lactide ); Chemical: pHEMA
