CA 2443766
The present invention is directed to a process for preparing a carbohydrate polymer which comprises polymerizing a sugar at a temperature below the point of substantial decomposition thereof and under reduced pressure in the presence of a catalytic effective amount of an organic acid selected from the group consisting of a monocarboxylic acid, a lactone of a monocarboxylic acid and arylol, while removing water formed during said polymerization, said organic acid being non-volatile and having only one acidic functionality and having no amino groups thereon. It is also directed t o the product produced therefrom.
L'invention concerne un procédé de préparation d'un polymère glucidique consistant à polymériser un sucre à une température inférieure au point de décomposition notable du sucre et sous pression réduite en présence d'une quantité catalytique efficace d'un acide organique choisi dans le groupe comprenant un acide monocarboxylique, un lactone d'un acide monocarboxylique et arylol, tout en ôtant l'eau qui est apparue au cours la polymérisation, cet acide organique étant non volatile, ne présentant qu'une seule fonctionnalité acide et ne possédant pas de groupe aminé. L'invention porte aussi sur le produit obtenu à partir de ce procédé.
