Description

technical field

[0001] The invention relates to the field of material preparation, in particular to a bicontinuous emulsion copolymerized porous material of methyl methacrylate and butyl methacrylate and a preparation method thereof. Background technique

[0002] Emulsion polymerization generally uses an emulsifier to disperse the monomer in water to form micelles, and the polymerization reaction is initiated by the initiator entering the micelles from water. According to the different ratio of water phase, the emulsion is divided into forward emulsion (oil-in-water), bicontinuous emulsion, inverse emulsion (water-in-oil). The shape of bicontinuous emulsion is similar to that of sponge, and the two phases penetrate each other but are connected. Microemulsion polymerization is the polymerization reaction of single-chain molecules or low-chain molecular polymerization reactions of transparent or translucent, low-viscosity and anisotropic stable systems containing appropriate ...
