摘要： Modified galactomannans are described having a total molar substitution exceeding 0.7 and containing an average of between 0.7 and 4 hydrophilic substituents and between 0.0001 and 0.02 hydrophobic substituents per anhydroglycosidic unit, the molar ratio of hydrophilic to hydrophobic substituents being between 35:1 and 40,000:1.A process for their preparation is also described.When dissolved in water, the compounds of the invention have the property of modifying the rheological properties of aqueous solutions by increasing their viscosity and their suspending properties, thus making them particularly suitable for industrial use in the paint, paper, and ceramic production sectors and as printing aids in the textile field, as aids in the preparation of fluids used in hydrocarbon research and production, and generally in any application in which such properties are required.

摘要： A new class of polymeric or polymerizable aromatic-aliphatic ketones, the preferred of which are: 2-hydroxy-2-methyl(4-vinylpropiophenone), 2-hydroxy-2-methyl-p(1-methylvinyl)propiophenone, p-vinylbenzoylcyclohexanol, p-(1-methylvinyl)benzoyl-cyclohexanol and their oligomerization and polymerization products, they being suitable for use as photoinitiators for the photopolymerization of ethylenically unsaturated monomers and prepolymers.Said ketones are produced by subjecting an aromatic substrate, preferably a monomer or oligomer of styrene type, to the following reaction cycle: polymerization - acylation - alphachlorination - nucleophilic substitution with the formation of epoxyether - hydrolysis of the epoxyether; or to other reactions as modifications or alternatives to this cycle.The ketones according to the present invention have high efficiency as photoinitiators both with regard to the useful concentration to be used and with regard to the polymerization rate.
