A clear aspect of understanding the functionalities of injectable polymers lies in the properties of both, polymer precursors and resulting polymer network. The main characteristics of polymer precursors include viscosity which determines its flowability and ability to fill complex bone defects; reactivity, which influences the polymerization kinetics and curing time; and solubility, which affects its compatibility with biological environments. Additionally, the monomer should also possess biocompatibility and low toxicity to ensure safety during and after administration in the body. Viscosity of the polymer precursor is crucial as optimal shear-thinning properties are desirable to ensure polymer injectability through a syringe or catheter while maintaining its structural integrity and localization at injection site, i.e. self-healing. Previously, et. al, Samimi Gharaie et. al, Zandi et. al and Bertsch et. al studied the high shear-thinning properties among the polymers which bind or crosslink through physical interactions (electrostatic interaction, hydrophobic interactions, ionic interactions, hydrogen bonding etc.) and dynamic covalent bonding (e.g. Schiff base, reversible Diels-Alder, disulfide bonds, and oxime chemistry) . Later on, Chandel et. al synthesized the polymer precursors with strong shearthinning properties composed of diazirine-modified hyaluronic acid (HA-DAZ) and dendritic polyethyleneimine (DPEI) which crosslinks under UV light through amide linkage and other physical interactions . Moreover, the resulting polymer network must possess good mechanical strength to prevent stress shielding and promote the remodeling of new bone tissue; degradation rate, which should be tailored to match the rate of new bone formation to avoid premature resorption or prolonged presence; and porosity, which could facilitates cell infiltration, nutrient diffusion, and vascularization. These properties are tunable and can be controlled easily by the appropriate selection of monomer type and their combination .
