摘要:
A rubbery composition is prepared by combining (A) a rubber component, (B) a cellulose, and (C) fluorene compound having a 9,9-bis(aryl)fluorene skeleton. The fluorene compound (C1) may be a compound represented by the following formula (1):
wherein a ring Z represents an arene ring, R 1 and R 2 represent a substituent, X 1 represents a heteroatom-containing functional group, k denotes an integer of 0 to 4, n denotes an integer of not less than 1, p denotes an integer of not less than 0. The rubbery composition has improved mechanical properties such as strength, elongation, and hardness.

With a view to realizing a titanium oxide composite that has a large surface area and that enables efficient transfer of electrons by covering a surface of rod-like or fibrous carbon with a covering layer comprising titanium oxide particles connected to one another, an object of the invention is to develop a material useful as an active material for dye-sensitized solar cells, and a process for producing the material; a porous titanium oxide-covered carbon material composition, and a process for producing the composition; and a photoelectric conversion element comprising the titanium oxide-covered carbon material or porous titanium oxide-covered carbon material composition.
摘要:
A polysilane having excellent functionalities (e.g., solubility in a solvent and reactivity) is obtained by introducing a structural unit of the following formula (1) to a polysilane through a reaction of a dihalosilane having a Si-H bond and adding a hydrosilylatable compound (e.g., a compound having a carbon-carbon unsaturated bond) to the Si-H bond.
In the formula, R 1 represents a hydrogen atom, an organic group, or a silyl group; and "n" denotes an integer of not less than 1.
