Abstract: This invention relates to a novel- 4-halogeno-5-(halo-genomethyl-phenyl)oxazole derivative; to a radiation-sensitive composition which, as the radiation-sensitive compound, contains a 4-halogeno-5-(halogenomethyl-phenyl)-oxazole derivative; and to a process for the preparation of the novel 4-halogeno-5- (halogenomethyl-phenyl)-oxazole derivatives. The novel 4-halo-geno-5-(halogenomethyl-phenyl)-oxazole derivative has the general formula I wherein Hal1 is a halogen atom, Hal2 is a chlorine or bromine atom, m is an integer from 1 to 3, n is an integer from 1 to 4, R1 is a hydrogen atom or a further CH3 mHal2m group and, R2 is a 1-valent or 2-valent, at most tetranuclear aromatic or heteroaromatic radical which may be partially hydrogenated and, at an unsaturated ring carbon atom, is linked, directly or via a chain which contains up to 4 exclusively unsaturated carbon atoms, to the oxasolyl part of the molecule according to the general formula I.

Abstract: This invention relates to a novel 2-(halogenomethyl-phenyl)-4-halogeno-oxazole derivative; to a radiation-sensitive composition which, as the radiation-sensitive compound, contains a 2-halogenomethyl-phenyl)-4-halogeno-oxazole derivative; and to a process for the preparation of the novel 2-(halogenomethyl-phenyl)-4-halogeno-oxazole derivatives. The novel 2-(halogeno-methyl-phenyl)4-halogeno-oxazole derivative has the general formula I I wherein Hal1 is a halogen atom, Hal2 is a chlorine or bromine atom, m is an integer from 1 to 3, n is an integer from 1 to 4, R1 is a hydrogen atom or a further CH3-mHal2m group, and R2 is a 1-valent or 2-valent, at most tetranuclear aromatic or heteroaromatic radical which may be partially hydrogenated, and at an unsaturated ring carbon atom, is linked, directly or via a chain which contains up to four exclusively unsaturated carbon atoms, to the oxazolyl part of the molecule according to the general formula I.

Abstract: The invention relates to a process for the preparation of activated chitosans in which a chitosan is reacted with an acid to form a salt and preferably subsequently with a base. The addition of acid and, preferably, of base in the activation is carried out in a suspending agent which substantially prevents dissolution of the chitosan salts. Suspending agents which can be used are both aqueous solutions of inorganic salts and organic or aqueous-organic solvents. The invention also relates to a process for preparing both water-soluble and water-insoluble chitosan derivatives by reacting the activated chitosans with reagents which are generally suitable for reacting polysaccharides or amines.

Abstract: Low molecular weight cellulose ethers which are suitable as a coating material for solid metered units and as an additive in ceramic compositions or cosmetics formulations or as a polymerization auxiliary are obtained by irradiation of a mixture of a higher molecular weight cellulose ether and a base with electrons.
