    Abstract: A conjugated diene block polymer composed of blocks having a different microstructure from each other such that one block contains 20 to 60% by mole of 1,2- and/or 3,4-bonding, the other block contains 50 to 90% by mole of 1,2- and/or 3,4-bonding, the difference in the 1,2- and/or 3,4-bonding content between the both blocks is from 20 to 50% mole and the average content of 1,2- and/or 3,4-bonding in the polymer is from 50 to 85% by mole. The block polymer has a high wet skid resistance and a low dynamic heat generating property, and is very useful as a material for automobile tires.

    Abstract: Processes for preparing 1-benzyl-4-[(5,6-dimethoxy-lindanon)-2-yl]methylpiperidine (donepezil), which is useful as an intermediate for medicines, and for producing 1-benzyl-4-[(5,6-dimethoxy-1-indanon)-2-yl]methylpiperidine hydrochloride (donepezil hydrochloride), which is useful as a medicine. The process for donepezil hydrochloride production comprises catalytically hydrogenating the compound represented by the structural formula (III) [1-benzyl-4-[(5,6-dimethoxy-lindanon)-2-ylidene]methylpiperidine] with a Raney nickel catalyst under mild conditions and subsequently treating it with hydrochloric acid. Thus, impurities are further diminished. The operations are simple and the process is suitable for industrial production.
