Abstract: An extremely reactive and highly copolymerizable hexafluoropropylene oxide oligoether derivative, to give bi- or ter-polymers with fluoroolefins and perfluoroalkyl vinyl ethers, which is represented by general formula: ##STR1## wherein X is a fluorine atom or trifluoromethyl group; and n is an integer of 2-5.

Abstract: A system for moving a television set has a carrier slidably mounted in a casing. The television set is pivotally mounted in the carrier at a front portion of the carrier. A carrier driving motor and a television set rotating motor are provided. A memory is provided for storing positions of the carrier and an angular position of the television set. A control unit is provided for controlling the carrier driving motor and the television set rotating motor in accordance with the positions stored in the memory for moving the carrier between a forward position and a backward position in the casing and for rotating the television set between a downward position and a standing position. Thus the television set is moved between a retracted position in the casing and the standing position outside the casing.

Abstract: The present compound is a novel perfluoropolyether represented by the following general formula: ##STR1## wherein m is an integer of 1 to 3 and n is an integer of 2 to 6. This compound is quite useful as an inert liquid used as a heat transfer mediums in the filed of electronic materials.

Abstract: A curable silicone composition comprising:(A) an alkenyl group-containing organopolysiloxane containing silicon-bonded alkenyl groups and a silicon-bonded fluorine-containing substituent having the general formula (1):Rf--O--Y-- (1)wherein Rf is a perfluoroalkenyl group having 5 to 10 carbon atoms, and Y represents a divalent organic group,(B) an organohydrogenpolysiloxane, and(C) a catalyst for addition reaction between components (A) and (B). This composition can form a cured coating which adheres firmly to various substrates and has good release properties, stability in the release properties, water- and oil-repellency, and solvent resistance. The coating exhibits good release properties even against pressure sensitive adhesives comprising a dimetylpolysiloxane.

Abstract: Fluorinated cyclic organic silicon compounds of the general formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, and R.sup.5 are independently selected from alkyl groups having 1 to 6 carbon atoms and n is an integer of from 1 to 6 are novel and susceptible to ring-opening polymerization to form chain siloxane polymers having improved properties. The cyclic compounds are produced by reacting disiloxane diols with fluorinated organic silicon compounds in the presence of amine catalysts.

Abstract: A purification method of a fluorine-containing alkylethylene comprises reacting the fluorine-containing alkylethylene with powdered metallic zinc in the presence of an aqueous acetic acid solution. By this method, fluorine-containing alkyl iodide and fluorine-containing alkylethyl iodide, contained as impurities in the fluorine-containing alkylethylene, can be removed effectively, for example, to a level of 1 ppm or below.
