Procedure

Then, for the antioxidant, a 2:1 mixture of (Dupont Methacrole™ 2462, c1) produced by reacting t-butyl diethanol amine and methylene-bis-(4-cyclohexyl isocyanate) and Dupont Methacrole™ 2390, c2) produced by condensation polymerization of p-cresol and divinyl benzene were prepared in a DMAc solution as an antioxidation agent (concentration 35 wt %), and this was added with other additives to solution C1 (55 wt %)
