The compound of the folded ring structure in the present invention has a folded ring structure composed of an aromatic ring and a six-membered ring containing saturated carbon, and has good chemical stability; the bond dissociation energy of the saturated carbon C-H bond in the six-membered ring containing saturated carbon It is easy to transfer hydrogen atoms and inhibit the polymerization of macromolecular radicals, and has a good polymerization inhibition effect.

Description

technical field [0001] The invention belongs to the field of functional materials, and more particularly, relates to the application of a compound with a cyclic structure as a control agent for free radical polymerization. Background technique [0002] Radical polymerization is a common polymerization method. It has the characteristics of a long history of development, various types of applicable monomers, and adaptation to various initiation methods of photothermoelectricity. It is widely used in packaging, biology, additive manufacturing, functional composite materials and other fields. However, the preservation of free-radical polymerization monomers, the preservation of adhesives, the maintenance of material physical properties, the regulation of kinetics and rheology, and the improvement of polymer structure and properties all require the addition of an appropriate amount of free-radical polymerization control agents. [0003] Commonly used free radical polymerization c...

Problems solved by technology

Although they have a good ability to regulate free radical polymerization reactions, they usually have high reactivity and are prone to redox reactions or chemical reactions involving metals, resulting in many unfavorable factors: 1) The chemical reaction of the control agent is converted into other compounds , resulting in the reduction or loss of the ability to regulate free radical polymerization (Photosynth.Res., 1985, 335-348); 2) The control agent in the monomer affects the chemical reaction process of the target, resulting in unnecessary side reactions or changes in the final reaction Product (Chem.Phys.Lett., 2009, 235-239); 3) The control agent reacts chemically after the material is formed, causing the physical properties (such as color, light transmittance) of the material to change (Prog.Polym.Sci ., 1992, 953-1044)
