Versuchsvorschrift

Polymethoxyethyl acrylate having a constitutional unit of the above formula (1) in which R1 is hydrogen, R2 is a methyl group and m is 1 was synthesized. Specifically, 15 g of methoxyethyl acrylate was polymerized in 60 g of 1,4-dioxane at 75° C. for 10 hours with nitrogen bubbling by using azobisisobutyronitrile (0.1% by mass) as an initiator. After the polymerization was completed, the resultant was added dropwise to n-hexane to form a precipitate, and thus the product was isolated. The product was dissolved in tetrahydrofuran, the resulting solution was purified with n-hexane twice, and the resultant was dried under reduced pressure for a whole day and night. Thus, a clear and colorless polymer with high viscosity was obtained. The yield rate was 76%. As a result of analysis of the thus obtained polymer by gel permeation chromatography (GPC), the polymer was found to have a number average molecular weight of 15,000 and a molecular weight distribution (Mw/Mn) of 3.4.
