In either case, there is a problem in that polymer scale adheres to the inner surface of the polymerization vessel. Due to this scale adhesion, the heat transfer efficiency of the polymerization vessel wall decreases, the product yield decreases, and the quality decreases due to the contamination of peeled scale into the product.
Many undesirable disadvantages arise, such as the labor required for peeling off scale and the time required for peeling off, such as a reduction in the operating rate of the polymerization reactor. To solve these problems,
Many compounds that prevent scale formation and adhesion have already been proposed, but they have advantages and disadvantages, and no suitable solution has yet been found.

Since the product (C) is only contained in a small amount when synthesized by the method of Example 1, when the compound is used as a coating agent for preventing scale adhesion, the mixture as it is is sufficient. It is very convenient to use and operationally.
