    摘要: A process for the preparation of a non-birefringent optical resin, characterized by copolymerizing a monomer mixture consisting of the following monomers (A) to (E) at such a ratio as to give the resin having an absolute value of orientational birefringence of less than 1×10−6; wherein (A): 5 to 40 wt % of a methacrylic or acrylic ester having a C5-C22 aliphatic hydrocarbon group in the ester moiety; (B): 50 to 80 wt % of methyl methacrylate; (C): 5 to 40 wt % of an N-substituted maleimide; (D): 0 to 30 wt % of benzyl methacrylate; (E): 0 to 10 wt % of a monomer copolymerizable with these monomers, and optical elements made by using the resin prepared by this process.
