Title: Production of poly(3-mono or 3,5-dihalogen-substituted-4-acetoxy or hydroxystyrene)
Inventor: ASLAM MOHAMMAD
IPC: C08F12/00
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To obtain a poly(halogen-substituted-4-hydroxystyrene) by reacting 4-hydroxyacetophenone with a halogenated reagent to give a corresponding 3-mono or 3,5-dihalogen-substituted derivative, esterifying the derivative, reducing the ester to give an ethanol compound, dehydrating the ethanol compound to give a styrene compound, subjecting the styrene compound to radical polymerization to give a polymer, and hydrolyzing the polymer. SOLUTION: 4-Hydroxyacetophenone represented by the formula (wherein R1 is H or a 1-10C alkyl; and R2 and R3 are each H, alkyl, alkoxy or halogeno) is reacted with a halogenated reagent to give a corresponding 3-mono or 3,5- dihalogen-substituted-4-hydroxyacetophenone, which is esterified to form 4- acetoxyacetophenone. This ester is reduced with a sufficient amount of a reducing agent to give acetoxyphenyl ethanol, which is dehydrated to give 4- acetoxystyrene. The 4-acetoxystyrene is subjected to free-radical polymerization to give a polymer having a molecular weight of 1,000 to 800,000, and this polymer is hydrolyzed to give an objective material.

Filed: 1990-10-05
Abstract: PURPOSE:To simply form an interlayer insulating film excellent in flatness, by performing reflow after an overhang shape is improved by sputter-etching the interlayer insulating film. CONSTITUTION:When a BPSG film 4 is grown on a polycrystalline silicon wiring 3 by a normal pressure CVD method, the BPSG film 4 is formed on an overhang of a step-difference part. When sputter-etching is performed by Ar ion, the shoulder part of the step-difference part is etched at an angle of 45 deg., and the overhang shape is improved. Reflow is performed by heat treatment in an N2 atmosphere. Since the shape before reflow is excellent, the flatness after reflow is also excellent. The BPSG film 4 in the flat part is not so much etched and the shape is improved, so that the BPSG film 4 does not become extremely thin when over-etching is performed, and the breakdown strength is not deteriorated.

Abstract: PURPOSE:To quickly and simply erase an undesired picture by providing an erasure mode setting means, an erasure signal generating means, a recording/ erasure signal supply switching means and a switching control means. CONSTITUTION:A video signal is recorded on a magnetic disk 68 by the pickup in the standard mode and if the video signal is not desired, the overwrite mode is selected by the depression of a switch 204. An analog switch 200 is changed over by the control of a control circuit 70 to allow an erasure signal generating circuit 202 to raise a signal. The signal is given to a magnetic head 62 via a recording preamplifier 60 and overwritten onto the video signal recorded already to erase it. Prior to the pickup, since the control circuit 70 discriminates the presence of recording, the new video signal is not overwritten on the track. Moreover, the frequency of the erasure signal is selected to the frequency in the band of the video signal.
