  • Patent number: 9012122
    Abstract: A modified novolak phenolic resin is obtained by reacting a novolak phenolic resin containing at least 50 wt % of p-cresol with a crosslinker. This method increases the molecular weight of the existing novolak phenolic resin containing at least 50 wt % of p-cresol to such a level that the resulting modified novolak phenolic resin has heat resistance enough for the photoresist application.

  • Patent number: 9006465
    Abstract: An epoxy group-containing a fluorene compound has a methallyl group at the end thereof and is represented by the following general formula (1): wherein R represents a hydrogen atom or a methyl group. The compound gives a compound excellent in regioselectivity at the time of hydrosilylation with a Si—H containing organosilicon compound, with a less formed amount of an internally added ? adduct, as compared with the conventionally known fluorene compound having an allyl group, so that heat resistance of the resulting organosilicon compound is expected to be improved whereby it is a useful compound.
