Abstract: Copolymers of olefinically unsaturated monomers, wherein at least one of the monomers is an isomer mixture of a cyclic or polycyclic olefinically unsaturated compound, which mixture contains a mass fraction from 8 to 50 per cent of at least one isomer of the main component in addition to this main component. The copolymers are useful, for example, in coating compositions.

Abstract: HOECHST AKTIENGESELLSCHAFT - Werk KALLE - ALBERT 89/K 013 9 February 1990 WLK-DI.Z.-ge MAGNETOOPTIC LAYER AND A PROCESS FOR ITS FABRICATION The magnetooptic layer made from rare-earth metals and transition metals exhibits a gradient in the alloy composition over the layer depth, and has a coercive field strength of more than 8 kOe in a temperature range .DELTA.T = 100.degree.C around the compensation temperature Tcomp. The fabrication is done using a dynamic sputtering process, in which the substrates to be coated are led past one or a plurality of sputter targets, which are arranged in a common plane parallel to the track of the substrates. A mask is located between the sputter targets and the substrates. (Fig- 1)

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.

Abstract: A photoconductive material, which is preferably in the form of a layer in an electrophotographic material, comprises (1) a polymerised heterocyclic vinyl compound, (for example poly-N-vinylcarbazole) or a polycondensed carbocyclic aromatic compound (for example a bromopyrene resin) as photoconductor, (2) an electron acceptor, (3) a subsequently crosslinkable binder and, (4) optionally, additives which improve the adhesion and/or the surface structure of the layer; wherein, the electron acceptor is present in an amount from about 0.1 to 0.5 mol per monomer unit of the photoconductor and the binder is present in an amount from about 30 to 120 parts by weight per 100 parts by weight of the photoconductor. A process for the preparation of the photoconductive layer is also described.

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: Copolymers comprising from 5 to 50 % by weight of one or more glycidyl esters of saturated aliphatic C4-C30-monocarboxylic acids containing a tertiary or quaternary alpha -carbon atom and from 95 to 5 % by weight of at least two olefinically unsaturated, copolymerisable monomers, of which at least one contains at least one carboxyl group. The copolymers are characterised by an OH number of from 50 to 250 mg of KOH/g, a solution viscosity of from 15 to 2000 mPa s (50 % strength solution at 23 DEG C), a mean molecular weight (weight average Mw) of less than 8600 g/mol and a nonuniformity of less than 3.4. The copolymers according to the invention are particularly suitable as binder components for high-solids coating compositions.
