Biodegradable cross-linked poly(trimethylene carbonate) networks for implant applications: Synthesis and properties

A structural interpretation of the two components governing the kinetic fragility from the example of interpenetrated polymer networks

“…For each composition, the degree of swelling and the gel percentage were measured at ambient temperature after immersion in acetone following the same procedure as Yang et al The elastic modulus was determined at ambient temperature, about 298 K, from tensile tests (the curves are shown in Butterfield et al). The values of these parameters are given in Table , with the uncertainties calculated from repeatability.…”

Synthesis of spirocyclosiloxanes for transparent copolymer thermosets

“…The ability of the spirocyclosiloxane to crosslink all kinds of cyclic molecules to generate highly transparent elastomers is unrivalled by other multiple ring cyclic molecules. For example, we synthesized a 2,2′‐bis(tris‐methylene carbonate‐5‐yl)‐butylether, a double‐ring cyclic carbonate crosslinker, and tested its ability to gel these single‐ring cyclic molecules at similar conditions. None resulted in transparent free‐standing films, and instead hazy gel‐like materials were obtained as shown by the control sample in Figure (a).…”

Synthesis, characterization and in vivo drug delivery study of a biodegradable nano-structured molecularly imprinted polymer based on cross-linker of fructose

“…It is proved that cross-linked polymers are normally stable so during degradation, they are able to protect their dimensions for longer time. These polymers demonstrate a homogenous degradation and tunable biodegradability that can be directly adjusted by cross-linking density [38,39]. Furthermore, biodegradable cross-linked polymers enjoying some other desirable advantages in medical applications like prolonged release of drug [40], excellent biocompatibility [41], and controllable drug release [42].…”
