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.

Abstract: Copolymers (I) of olefinic monomer(s) comprise an isomeric mixt. of esters of isobornyl alcohol with an alpha , beta -unsatd. acid. The isomeric alcohol mixt. contains: (a) not more than 92% isoborneol, (b) at least 3.5% iso-fenchyl alcohol, and (c) at least 1% pseudo-bornyl alcohol. Also claimed are: (i) a process for the prodn. of (I) by bulk polymerisation in the presence of aliphatic azo cpds., diacyl peroxide, alkyl per-esters, alkyl hydroperoxide, dialkyl peroxide or peroxy-di-carbonate as radical initiators; and (ii) a process for the prodn. of water-dilutable polyacrylate dispersions by: (A) dissolution of (I) in a water-dilutable organic solvent, followed by: (B) partial or complete neutralisation, and (C) dilution by adding water or stirring the soln. into water.

Abstract: A radiation-curable composition which comprises a compound that forms an acid under the action of high-energy radiation and an acid-hardening substance, wherein the compound forming an acid contains aromatically linked chlorine or bromine and has a pKa value below 12. The composition and the recording material prepared therefrom display increased sensitivity, improved resolution and a high etch resistance after development.
