METHODS OF PREPARING HOLLOW ACRYLATE POLYMER MICROSPHERES

摘要

A one-step emulsification process for preparing aqueous suspensions of hollow, acrylate polymer microspheres conducted in the presence of at least one acid that is not free radically polymerizable. Surprisingly, the use of such an acid eliminates the previous requirement of using a polar copolymerizable monomer in the one-step emulsification process. The hollow acrylate polymer microspheres prepared from the process of the invention may be tacky of tack-free.
