A solvent-free adhesion-promoting chain extender, a preparation method therefor, and an application thereof. The preparation method comprises the following steps: mixing an aromatic vinyl monomer, an acrylate-based monomer, an initiator, and water, then heating the mixture for polymerization, and subjecting the product to a secondary reaction by means of a twin-screen extruder for granulation, so as to prepare a solvent-free adhesion-promoting chain extender. The obtained epoxy functionalized chain extender can be applied to a recycled material of a polyester structure and can be used for the repair and growth of molecular chains of biobased and biodegradable plastics of a polyester structure. The preparation method features no use of a solvent in a process route, low investment, easily available apparatuses, low emission in the process route, and simple process control; in addition, the product has stable composition and is easy to use, and thus can be widely used in the fields, such as medical treatment, packaging, home appliances, automobiles, and aviation. |
