Abstract: The invention aims at providing fluorinated polymers exhibiting excellent light transmission in the vacuum ultraviolet region of 193 nm or below; processes for preparation of monomers suitable for the production of such polymers and the fluorinated polymers; and use of the polymers. The fluorinated polymers comprise at least repeating units represented by the general formula (1) and exhibit ultraviolet absorption coefficients of 3.0 mu m or below at 157 nm: (1) wherein R to R are each fluoro, fluorinated C1-20 alkyl, or the like; X is CR R -, -NR -, or PR - (wherein R and R are each fluoro, fluorinated C1-20 alkyl, hydrogen, -O-, -S-, C1-20 alkyl, or the like), with the proviso that at least one of R to R and X is fluoro or a fluorine-containing group; and n is an integer of 0 to 3.

Abstract: An object of the invention is to provide a solid polyaluminoxane composition suitably used as a cocatalyst and a catalyst carrier in combination with an olefin oligomerization or polymerization catalyst, without the use of solid inorganic carriers such as silica. The solid polyaluminoxane composition of the invention includes a polyalkylaluminoxane and a trialkylaluminum, and has a solubility in n-hexane at 25°C of less than 0.50 mol% as measured by a specific method (i), a solubility in toluene at 25°C of less than 1.0 mol% as measured by a specific method (ii), and a 13 mol% or more molar fraction of alkyl groups derived from the trialkylaluminum moieties relative to the total number of moles of alkyl groups derived from the polyalkylaluminoxane moieties and the alkyl groups derived from the trialkylaluminum moieties as measured with respect to tetrahydrofuran-d 8 soluble components by a specific method (iii).
