Title:
水膨張性ポリマービーズ
Document Type and Number:
Japanese Patent JP2014524498
Kind Code:
A
Abstract:
The present invention relates to a process for the emulsifier-free preparation of water expandable polymer beads. The process comprises the steps of: a) providing an emulsifier-free monomer composition comprising styrene and a polar comonomer comprising a carbon-to-carbon double bond, b) prepolymerizing the monomer composition to obtain a prepolymer composition comprising styrene, the polar comonomer and their copolymer, c) adding an aqueous dispersion of nanoclay to the prepolymer composition to obtain an inverse emulsion, d) suspending the inverse emulsion obtained by step c) in an aqueous medium to yield an aqueous suspension of suspended droplets and e) polymerizing the monomers in the droplets of the suspension obtained by step d).
