Manufacturing method of pearl polymer, and PAMA- plastisol having the pearl polymer, dental materials, porous plastic mold, molding materials and moldings

摘要

The present invention provides a process for preparing bead polymers having an average particle size of 1 to 40 mum, which includes:contacting:at least one polymerizable mix which includes at least 50% by weight of at least one (meth)acrylate monomer,at least one aluminum compound, andan aqueous phase,to prepare a mixture;dispersing the mixture at a shear rate=103 s-1 to form a dispersion, wherein the dispersion is stabilized by the aluminum compound; andpolymerizing to produce bead polymers having an average particle size of 1 to 40 mum.
