简介

The   synthetic plastics continue to accumulate in nature, leading to increased   demand for the development of alternatives. Biodegradable polymers prepared   using raw materials from natural resources are good substitutes for commonly   used petroleum-based materials. Polyesters such as polycaprolactone,   polyvalerolactone, and polylactide are most widely studied biodegradable   polymers for biomedical, pharmaceutical and packaging applications. The most   common method to synthesize polyesters is the ring opening polymerization of   cyclic monomers. Mostly, metal-based catalysts or organocatalyst are used for   ring opening polymerization of cyclic monomers. However, in the case of biomedical applications,   the separation and recovery problems associated with soluble metal complexes   have been extensively pursued the synthesis of heterogeneous catalysts as potential   initiators for polymerization. In other words, the use of heterogeneous   catalysts develops exponentially because they are easier to separate,   regeneration, and reuse making them more attractive than homogeneous   counterparts. To keep this in mind and to focus on the metal-free polymers,   we designed and synthesized different MOFs and their derivatives, which have   been used for ring opening polymerization of cyclic esters.
