The controllability of ester leveling agents is accomplished by modifying the molecular weight and polarity. The compatibility of homopolymers is not as good as that of copolymers. For example, homopolymers usually have poor compatibility with resins used in epoxy, polyester, polyurethane and other coatings. If they are physically mixed, the surface condition will be poor. It is a matt coating film, so homopolymer is not suitable as a leveling agent. Most of the leveling agents use copolymers, which can be terpolymers or modified copolymers. only the copolymers can change the polarity and glass flower temperature of the polymer through different monomers. The current regulations can be divided into two major systems, one is a "permitted list" that "exhaustively" lists permitted additives, and the other is a "prohibited list" that lists prohibited additives. After years of practice, the "banned list" was found to have a big flaw: the lack of binding force on the new. When a new type appears, because it is not on the existing "prohibited list", it can be applied to food packaging materials at will, and the regulations cannot. Therefore, the original "prohibited list" and the "permitted list" system have been changed. Europe and the United States have adopted the "licensed list" system. The 2003 version of the "Sanitation for the Use of Auxiliaries for Food Containers and Packaging Materials" has a total of 65 kinds of additives in the approved list.
