Description
The present invention relates to polymethylmethacrylate/sulfonated polystyrene compounded water-base microemulsion and preparation method thereof.
Be meant that from the aggressiveness aqueous microemulsion superpolymer is dispersed in the stable aqueous dispersion that forms in the water continuous phase with the ultrafine particulate form.Because the superpolymer aqueous microemulsion does not contain the organic solvent of (or containing a small amount of), environment is not polluted not insulting health.Therefore, it is widely used in the water-based paint industrial circle.In addition, because the micro polymer particle size is at nano level in the aqueous microemulsion, close with the bioprotein size, the difference in functionality group makes it have multiple different function on the microparticle surfaces band if make by chemical process, then it is at the medicament slow release putting material, and aspects such as microcapsule and medical diagnosis medicament have broad application prospects.
As everyone knows, single polymer properties all has its relative merits, and the method by polymer blending can remedy polymkeric substance shortcoming separately.But, because uncompatibility between polymer blend causes the intermingling material performance degradation.Be mutual tangled structure between the molecular chain if the phase farmland size that can reduce blend to nano level or micron order, makes to be similar between blend components, just can obviously improve the consistency between blend components, improve performance of composites.
The object of the present invention is to provide a kind of polymethylmethacrylate/sulfonated polystyrene compounded water-base microemulsion and preparation method thereof.Polymethylmethacrylate/the sulfonated polystyrene compounded water-base microemulsion of preparation has satisfactory stability and particle size.
The present invention utilizes phase inversion technique, sulfonated polystyrene is emulsified into the nano level aqueous microemulsion, be reacting environment with sulfonated polystyrene particulate nuclear inside again, cause the polymerization of lipophilicity monomers methyl methacrylate with initiator, prepare stable polymethylmethacrylate/sulfonated polystyrene compounded water-base microemulsion.The mean particle dia of prepared microemulsion is between 15～500 nanometers.
The preparation process of polymethylmethacrylate/sulfonated polystyrene compounded water-base microemulsion is: with sulfonation degree is that the sulfonated polystyrene ionomer of 3mol%～15mol% is dissolved in organic solvent (as: acetone, pimelinketone, toluene, methyl alcohol or their mixed solvent), add emulsifying water to phase reversion (the system specific conductivity is undergone mutation and characterized), form grain diameter at the stable sulfonated polystyrene aqueous microemulsion of tens～hundreds of nanometer, add the lipophilicity monomers methyl methacrylate and account for the initiator of monomer weight 0.2～10% (as benzoyl peroxide BPO, Diisopropyl azodicarboxylate AIBN), the weight ratio of monomers methyl methacrylate and sulfonated polystyrene is 1: 0.1～10; Stirring makes it penetrate into sulfonated polystyrene particulate nuclear inside, is warming up to 70～90 ℃, and reaction 4～10h causes methyl methacrylate polymerization, promptly gets polymethylmethacrylate/sulfonated polystyrene compounded water-base microemulsion.
Polymethylmethacrylate/the sulfonated polystyrene compounded water-base microemulsion of the present invention's preparation, the emulsion particle particle diameter arrives several hundred nano-scales tens, the size of two kinds of interpolymer interactions is at molecular level, has consistency preferably, the film that emulsion became has better toughness and intensity than with the prepared blend membrane of solution blending process, can be used as paper lustering agent, paper plastic uptake buffing oil, replacing present solvent borne paper lustering agent and paper plastic uptake buffing oil, is the new paper auxiliary agent of a kind of free of contamination environment-friendly type.
