Abstract: A process for preparing compounds of formula (I) comprising radical addition of RfI to 3-(allyloxy)methyl-3-alkyloxetane (1) wherein R is C1-3 alkyl and Rf is C1-18 linear or branched fluoroalkyl. The compounds of formula (I) are useful as intermediates for preparing various fluorine-containing functional materials.

Abstract: Disclosed is water- and oil-repellent powder for cosmetic, containing a homopolymer of a polyfluoroalkyl group-containing (meth)acrylate (I) or a copolymer of the polyfluoroalkyl group-containing (meth)acrylate (I) and an alkyl (meth)acrylate (II) and/or a silicone macromonomer (III). A cosmetic containing water- and oil-repellent powder for cosmetic is superior in water- and oil-repellency and feel in use, and has almost no change of makeup.

Abstract: A leather modifier containing a compound which is obtainable through a reaction of an ethylene oxide derivative having a fluorine-containing group with a phosphorus compound is disclosed. A leather treated with the modifier has much improved properties.

Abstract: The present invention provides an agent for treating textile having a combination of a modifying agent and a fixing agent, wherein the modifying agent is a fluorine-containing phosphoric acid derivative represented by the formula wherein R.sup.1 and R.sup.2 are, same or different, a hydrogen atom or R.sub.f --(CH).sub.2).sub.m -- (wherein R.sub.f is a saturated or unsaturated, linear or branched fluorine containing aliphatic group having 4 to 20 carbon atoms in which an oxygen atom, a nitrogen atom, a sulfonyl group and/or an aromatic ring may intervene between the carbon atoms; and m is 1 or 2) (R.sup.1 and R.sup.

Abstract: A tanned leather treated with a fatliquoring agent in combination with a fluorine-containing oil, which has good touch, water resistance, water- and oil-repellency, washing resistance, and which is not discolored or faded by dry cleaning.

Abstract: An organism which generates energy through the decomposition of cellulose such as termites can be selectively destroyed with a fluorine-containing glycoside of the formula: ##STR1## wherein n is an even number of 2 to 20, and m is an integer of 0 to 5.

Abstract: A fluorine-containing benzophenone derivative of the formula: ##STR1## wherein R.sup.1 is a group of the formula: --OM (in which M is hydrogen or alkali metal), lower alkoxy, lower acyloxy, a group of the formula: ##STR2## (in which R.sup.3 and R.sup.4 are same or different and hydrogen or lower alkyl) or a group of the formula: --OCH.sub.2 COOR.sup.5 (in which R.sup.5 is hydrogen, lower alkyl or alkali metal); R.sup.2 is halogen, nitro, chlorosulfonyl, sulfo, trifluoromethyl or a group of the formula: --SCF.sub.2 H; and m and n are each an integer of 1 to 4 provided that the sum of m and n is not more than 5 having selective herbicidal activities on grasses and crops.
