摘要

This invention discloses a raw-material composition for pregellation which has a radically polymerizable thermosetting resin as a substantially main component thereof and contains at least one compound selected from the group consisting of 2,4-diphenyl-4-methyl-1-pentene and terpinolene, at least one low temperature-decomposing organic peroxide possessing a 10-hour half-life temperature in the range of 35 DEG C to 80 DEG C, and at least one high temperature-decomposing organic peroxide selected from the group peroxyketals, peroxyesters, and dialkyl peroxides and possessing a 10-hour half-life temperature falling in the range of 80 DEG C to 140 DEG C and exceeding that of the lower temperature-decomposing organic peroxide; a method for the preparation of a pregel by the heat-treatment of the raw-material for pregellation; a pregel produced by the method; method for the production of a molded material which comprises molding the pregel in a prescribed shape and heat-treating the shaped mass of pregel; and a molded material produced by the method.
