Preparation and degradation characteristics of biodegradable elastic poly (1,3-trimethylene carbonate) network

As soft-tissue materials, poly (1,3-trimethylene carbonate) (PTMC) must have adequate mechanical properties as well as good shape stability under long-term cyclic deformation conditions. With trimethylolpropane triacrylate (TMPTA), pentaerythritol triacrylate (PETA), and pentaerythritol tetraacrylate (PET4A) as crosslinking agents, PTMC networks were prepared by gamma irradiation under vacuum to improve mechanical properties and resist creep....
