Abstract:
The present invention is applicable to the field of polymer material preparation, and provides a method for preparing polymer hollow microspheres, the steps are as follows: mixing a styrene-based monomer A, an acrylic monomer B, and an acrylate monomer C with a initiator, and reacting to prepare a seed emulsion; maintaining the temperature of the seed emulsion unchanged, mixing the styrene-based monomer A, the monomer C, and a sulfur-containing acrylic monomer D with the initiator, continuously dripping to the seed emulsion, to obtain a product; adding alkaline solution to the product, then adding acid solution, and finally neutralizing, to obtain hollow microspheres.

Claim (Index 6):
The preparing method according to  claim 5 , wherein the concentration of the alkaline solution is 5-20%, the alkaline solution is KOH or NaOH solution; the concentration of the acidic solution is 5 to 20%, and the acidic solution is hydrochloric acid, sulfuric acid or phosphoric acid solution.
