Manufacturing method of polymer emulsion for water resistant film

摘要

[1] The present invention provides a method for producing a polymer emulsion for a water-resistant coating film having excellent water resistance, by emulsion polymerization of a monomer (B) capable of radical polymerization in the presence of a compound (A) represented by the following formula (1), and [2] Step 1 and emulsion polymer obtained by emulsion-polymerizing the monomer (B) which can be radically polymerized in presence of the compound (A) represented by following formula (1), and obtaining an average particle diameter of 30 nm or more and 300 nm or less to a board | substrate It is related with the manufacturing method of the polymer coating film which has the process 2 to apply | coat and dry. [Wherein, R ¹ represents an alkyl group having from 16 to 24 carbon atoms, m represents an average added mole number of (CH ₂ CH ₂ O), 0.5 or more and 10 or less, and M represents a cation or a hydrogen atom.]
