ABSTRACT:
A polymer scale preventive agent for use in polymerization of a monomer having an ethylenic double bond, comprising at least one compound selected from the group consisting of agars and agaroses. A process of producing a polymer by polymerizing the monomer in a polymerization vessel having on its inner wall surfaces a coating comprising the scale preventive agent. Polymer scale deposition inside the polymerization can be effectively prevented, and polymers with high whiteness can be prepared. Moreover, the scale preventive agent no poisonousness and is highly safe.
