摘要:
A process for producing a 1,4-methano-1,4,4a,9a-tetrahydrofluorene composition in which the contents of two cyclopentadiene trimers each having a specific structure are regulated to 100 to 5,000 ppm, which comprises reacting cyclopentadiene and/or dicyclopentadiene with 2 to 50 mol of indene per mol of the diene with heating and purifying the reaction product by distillation. By using the composition as a feed material for various polymerizations, gelation in polymerization is inhibited and resins having excellent optical properties can be obtained.
