Polyvinyl acetate starch (PVA-based starch) is a starch derivative synthesized using polyvinyl acetate (PVA) as raw material through polymerization reactions. This material has garnered significant attention due to its unique properties and broad application prospects. The following is an article on polyvinyl acetate starch:

Abstract: Polyvinyl acetate starch (PVA-based starch) is a novel polymer material prepared via chemical reactions between polyvinyl acetate (PVA) and natural starch. It exhibits excellent physicochemical properties, biocompatibility, and degradability, promising widespread applications. This paper reviews the definition, structural characteristics, synthesis methods, application fields, and development trends of PVA-based starch.

1. Definition and Structural Characteristics Polyvinyl acetate starch is a polymer synthesized through cross-linking or etherification reactions between PVA and natural starch. Its molecular chains incorporate both PVA segments and starch segments, endowing it with good mechanical strength and flexibility. Additionally, the presence of starch ensures biocompatibility and degradability, making it suitable for biomedical applications.

2. Synthesis Methods The synthesis of PVA-based starch primarily involves solution polymerization, emulsion polymerization, and suspension polymerization. Among these, solution polymerization is most commonly used. In this process, PVA is dissolved in an appropriate solvent, followed by the addition of starch and an initiator. At suitable temperatures, the initiator decomposes to generate free radicals, triggering polymerization. As the reaction proceeds, the polymer precipitates, and the product is obtained after washing and drying.

3. Application Fields The exceptional properties of PVA-based starch enable its versatile applications:

(1) Biomedical Field: Due to its biocompatibility and degradability, it is used in drug delivery carriers, tissue engineering scaffolds, artificial blood vessels, and other biomedical devices.

(2) Textile Industry: Its film-forming ability and softness make it suitable for manufacturing waterproof yet breathable fabrics, protective clothing, and other textiles.

(3) Packaging Industry: With high tear resistance and transparency, it is employed in food packaging bags, beverage bottles, and other packaging materials.

(4) Agricultural Field: Its moisture-retention and adhesive properties allow applications such as seed coating and fertilizer encapsulation in agriculture.

4. Development Trends Advances in science and technology continue to expand the synthesis methods and applications of PVA-based starch. Future research will focus on enhancing its performance and reducing costs to meet demands across diverse fields. the development of green synthesis technologies offers new pathways for its production.

As a multifunctional polymer material, PVA-based starch holds immense potential. Through ongoing improvements in synthesis methods and expanded applications, it is poised to play a critical role in future technological advancements.
