314  US  10,031,419 B2  313  Synthesis was carried out according to the scheme below.  -continued  In the same manner as the resin HR-31, resins HR-1,  HR-24, HR-26, and HR-30 to HR-40 were synthesized.  Specific examples of the synthesized polymer structure,  composition ratio, weight average molecular weight (Mw),  and dispersity (Mw/Mn) are as described above.  Synthesis was carried out according to the scheme below.  Synthesis Example 4: Synthesizing Resin T for Top  Coat  Synthesis Example 3: Synthesizing Resin HR-31  1.08 g ofa compound (4), 19.77 g ofa compound (5), and  0.69 g of polymerization initiator V-601 (manufactured by  Waka Pure Chemical Industries, Ltd.) were dissolved in  92.09 g of cyclohexanone. 23.02 g of cyclohexanone was  put in a reaction container and dropwise addition thereto was  performed at 85° C. for 4 hours under a nitrogen gas  atmosphere. The reaction solution was heated and stirred for  2 hours and left to cool to room temperature.  P-13  OH  Mw:4600  Mw/Mn: 1.18  P-14  OH  Mw: 6700  Mw/Mn: 1.18  ------- HR-31  (1)  OH  (2)  (3)  OH  T-4  ------- The reaction solution described above was added drop› wise to 1350 g of heptane/ethyl acetate=S/2 (mass ratio) and  the polymer was precipitated and filtered. Using 400 g of the  heptane/ethyl acetate=S/2 (mass ratio), running washing was  performed on the filtered solid matter. After that, 9.55 g of  a resin (the resin (HR-31)) was obtained by reducing pres› sure and drying the solid matter after cleaning.  With regard to theresinHR-31, using GPC (manufactured  by Tosoh Corp.; HLC-8120; Tskgel Multipore HXL-M) with  THF as a solvent, the weight average molecular weight and  dispersity were measured. In addition, using NMR (manu› factured by Bruker BioSpin K.K.; AVANCEIII400 type), the  compositional ratio was calculated by $^{1}$H-NMR or $^{13}$C› NMR. The results are shown in Table 1 above.  32.5 g of l-methoxy-2-propanol was heated to 80° C.  under a nitrogen atmosphere. While stirring the liquid, a  mixed solvent of 1.53 g of monomer (1), 3.00 g of monomer  (2), 11.81 g of monomer (3), 32.5 g of l-methoxy-2- propanol, and 1.61 g of 2,2’-azobisiso butyric acid dimethyl  [V-601, manufactured by Waka Pure Chemical Industries,  Ltd.] was added dropwise for 2 hours. After finishing the  dropwise addition, the mixed solvent was further stirred at  80°  C. for 4 hours. After leaving the reaction liquid to be  cooled, 20.5 g of a resin T-4 for a top coat was obtained by  performing re-precipitation and vacuum drying using a large  amount of hexane.
