There is disclosed a composition for use in the formation of an active light waveguide comprising a fluorinated polyamic acid and an electro-optical material. The active light waveguide is manufactured by subjecting the fluorinated polyamic acid to imide ring closure into a fluorinated polyimide, and orienting the electro-optical material. The active light waveguide fabricated by using the composition for use in the formation of the active light waveguide can provide excellent electro-optical effect. The active light waveguide is extremely thermally stable and suitable to manufacture of electro-optical devices.

Composition for use in the formation of an active light waveguide,

A catalyst for hydroformylation of an olefin with H.sub.2 and CO is disclosed which includes an inorganic oxide carrier, and two or more catalytic metal components supported on the carrier, the metals of said catalytic metal components being cobalt and at least one auxiliary metal selected from rhodium, ruthenium, rhenium, iridium, platinum, palladium, copper, osmium and gold. By contacting a feed of an olefin, H.sub.2 and CO with the catalyst, the olefin is converted into an aldehyde and an alcohol.
