Method of transferring latex particles from an aqueous to an organic phase and making an impact resistant acrylic sheet |
摘要 |
Impact resistant compositions are prepared by the incorporation of acrylic rubber particles (or multi-stage emulsion polymer particles containing a rubbery layer) in a predominantly methyl methacrylate matrix. The emulsion particles are prepared in water as a latex stabilized with anionic groups. The particles are transferred to a methyl methacrylate medium by destabilizing the latex with a quaternary ammonium salt and optionally a di- or multivalent inorganic salt. Impact resistant compositions are prepared by separating the water from the methyl methacrylate layer and polymerizing the methyl methacrylate.
