  • Method for preparing spherical celluloid beads
    Patent number: 10711070
    Abstract: A wet chemistry method for preparing spherical celluloid beads by mixing a water-based suspension solution and a solvent based celluloid solution that is immiscible in the suspension solution. The two combined solutions create an “oil-in-water” type mixture where the dispersed phase consists of celluloid dissolved in solvent and co-solvent that is suspended in the continuous water phase. Agitation and removal of the solvent and co-solvent mixture produces spherical shaped celluloid beads.
