β¦ Synopsis
A resin with a high refractive index and a high Abbe number can be produced by radical polymerization of a polymerizable monomer mixture composed of essentially sulfur-containing aromatic methacrylates. An optical material composed of said resin is provided especially for lenses.

## Abstract A series of novel high refractive index episulfideβtype optical resins were prepared by ringβopening copolymerization of bis(Ξ²βepithiopropylthioethyl) sulfide (BEPTES) with episulfide derivative of diglydicyl ether of bisphenol A (ESDGEBA) and 2,4βtolylene diisocyanate (TDI), respective
C 2 -Symmetric 9,9 0 -spirobifluorene-containing polyesters (PEs) were synthesized by polycondensation of 2,2 0 -dihydroxy-9,9 0 -spirobifluorene (1) with bis(acyl chloride)s (2) at 230 C in diphenylether. The molecular weights of PEs 3ae3f were sufficiently high (M w 13,400e41,600). PEs displayed h
