In recent decades, polymer materials have become indispensable materials for various departments of the national economy, national defense construction, people’s lives, and even modern science and technology. During the production and processing of these materials, it is usually necessary to add some chemicals, generally called “auxiliaries”.
For polymer materials, additives are an important component, and their functions are diverse. Some additives can enable high-grade dry materials to maintain the excellent properties of polymers, prevent or delay Decorative materials and products age and deteriorate during processing, storage and use; some additives can improve the mechanical strength and certain physical properties of polymer materials and their products; some synthetic material additives can impart Polymer materials and their products have certain special properties, thereby expanding their scope of use; some additives can improve the indene addition performance and conditions of high-grade f materials. In short, the role of additives is extremely important for polymer materials and their development.
With the rapid development of petrochemical industry and high molecular chemical industry, the variety and output of polymer materials have increased rapidly, as well as the development of processing technology and the expansion of uses, the variety and output of additives have also increased. .There is an increasingly urgent need to study the relationship between the production, structure and performance of additives, as well as their application scope and methods.
Synthetic material additives used in the polymer materials industry , usually divided into two categories: synthetic aids and processing aids according to the scope of use. The former such as catalysts, initiators, polymerization regulators, polymerization inhibitors, etc.; the latter such as plasticizers, antioxidants, cross-linking agents, etc.
