COMPOSITE PARTICLES, METHOD FOR PRODUCING COMPOSITE PARTICLES, AND USE THEREOF |
| 摘要 |
There are provided a method for producing particles by suspension polymerization which ensures an excellent dispersion stability of the monomer and a simpler washing step, composite particles obtainable by this production method, and use of the composite particles. The method for producing composite particles includes a polymerization step of subjecting a monomer mixture which contains a polymerizable vinyl monomer to aqueous suspension polymerization in a presence of small polymer particles having a volume-average particle size of 20 to 500 nm, with a water-soluble cellulose compound adsorbing on surfaces of the small polymer particles, and thereby obtaining composite particles which contain the small polymer particles and large polymer particles greater than the small polymer particles. |

1. A method for producing composite particles comprising a polymerization step of subjecting a monomer mixture which contains a polymerizable vinyl monomer to aqueous suspension polymerization in a presence of small polymer particles having a volume-average particle size of 20 to 500 nm, with a water-soluble cellulose compound adsorbing on surfaces of the small polymer particles, and thereby obtaining composite particles which contain the small polymer particles and large polymer particles greater than the small polymer particles. |
