  • Method of producing powder
    Patent number: 6429283
    Abstract: The present invention provides a method of producing powder of e.g. a polycarboxylic acid-based copolymer efficiently at a high yield. The method of the present invention comprises forming a sticky thin-film of the polycarboxylic acid-based copolymer or the like on a support, reducing a stickiness of the said thin-film and powdering the said thin-film.
