Synthesis of Polymer (F-1)
A monomer solution was prepared by dissolving 79.9 g (70 mol %) of the compound (M-56) and 20.91 g (30 mol %) of the compound (M-75) in 100 g of 2-butanone, and further dissolving therein 4.77 g of dimethyl 2,2'-azobisisobutyrate as a radical polymerization initiator.
Next, a 1,000 mL three-neck flask containing 100 g of 2-butanone was purged with a nitrogen gas for 30 min, then heated to 80° C. with stirring, and the monomer solution prepared above was added dropwise over 3 hrs using a dropping funnel.
The time of the start of the dropwise addition was regarded as the time of the start of the polymerization reaction, and the polymerization reaction was allowed to proceed for 6 hrs.
After the completion of the polymerization reaction, the polymerization reaction solution was water-cooled to 30° C. or below.
This polymerization reaction solution was transferred to a 2 L separatory funnel, and homogeneously diluted with 150 g of n-hexane.
After the addition of 600 g of methanol, the components were mixed.
Then, after the addition of 30 g of distilled water, the mixture was further stirred, and then allowed to stand for 30 min.
Thereafter, the lower layer was collected to obtain a propylene glycol monomethyl ether acetate solution containing a polymer (F-1) (yield: 60%).
The polymer (F-1) had an Mw of 7,200, and an Mw/Mn of 2.00.
The result of 13C-NMR analysis indicated that the proportions of the structural unit derived from (M-56) and the structural unit derived from (M-75) were 71.1 mol % and 28.9 mol %, respectively.
