Degradable and Nanosegregated Elastomers with Multiblock Sequences of Biobased Aromatic Mesogens and Biofunctional Aliphatic Oligocarbonates

We have developed multiblock aromatic/aliphatic condensation polymers, comprising side-chain biofunctionalized aliphatic oligocarbonates and biobased aromatic ester triad mesogens up to 17 wt %. Nanosegregation of the mesogen-rich domains with diameters approximately 10 nm from soft polymer matrix is suggested by atomic force microscopy. The polymers exhibit rubberlike properties, unlike corresponding polycarbonate forming viscous liquid. These properties support interchain interactions between mesogens, which can serve as physical cross-linking. in significantly bolster tolerance organocatalytic hydrolysis methanolysis chains but are eventually degraded. show degradation behavior slightly faster than poly(L-lactide), whereas poly(ethylene terephthalate) remains intact under same condition. present study demonstrates efficacy incorporated into sequences biodegradable polycarbonates enhance their while retaining degradability.
