摘要： A method of washing pre-expanded particles having a substantially water insoluble inorganic compound attached thereto by contacting the pre-expanded particles with an aqueous washing solution of a water soluble compound. The water soluble compound has a solubility with water of at least 1 g/100 g of water and has 1-500 surface bonding functional groups and 1-500 hydrophilic functional groups. At least one of the surface bonding functional groups of the water soluble compound attaches to the water insoluble inorganic compound.
