Precipitation polymerization process is to dissolve monomer and initiator in a solvent in general, raw after polymerisation starts
At polymer solubility in a solvent it is extremely low, such polymer can be precipitated out from homogeneous reaction system.Because of precipitation
Lack some components (such as emulsifier or dispersant) for reducing surface energy, thus the polymer meeting being precipitated out in polymerization system
Because higher surface energy agglomerates into rapidly block materials.Therefore the usual monomer concentration of precipitation polymerization is all very low (5vol%),
Yield is not also high, and needs matched dicyandiamide solution.The precipitation polymerization of polyfunctional monomer is due to being crosslinked, solvent selection
Range smaller, the overwhelming majority reported at present is acetonitrile, and this kind of organic solvent of ethyl acetate is more toxic, also not to environment
It is friendly.
The method of some precipitation polymerizations such as solvent heat precipitation polymerization process, reacts under high-temperature and high-pressure conditions, generates
Polymer core dissolubility and Brownian movement rate it is all higher than under normal temperature and pressure, reduce the probability of core coalescence so that core
Stability increases, thus can obtain dispersed preferable polymethyl methacrylate glycol ester microballoon (PEGDMA microballoons).But
Solvent thermal reaction system is because carried out under closed environment, and pressure can increase system during the reaction, therefore is filled to experiment
It sets and experiment safety has very high requirement.Such as think to synthesize PEGDMA microballoons at normal temperatures and pressures, causes system and solvent
System these two aspects wants matched just right, just can guarantee that the coalescence probability of the polymer core of generation is sufficiently low, such ability
Obtain polymer microballoon material.High-energy ray radiation-initiated polymerization is used in the present invention, and dicyandiamide solution is using specific proportioning
Alcohol-aqueous solvent, the problem of not only solving room temperature initiation reaction, and keep the dissolubility of polymer core in a solvent best, make
The probability of collision coalescence between them reduces, and further improves its yield and dispersibility.
