DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 40 A no. of phosphonocarboxylic acids, including those as good crosslinking agents for cellulose, give a clear correlation between this property and the esterification ability with alcs. such as (tetrahydro-2-pyranyl)methanol and trans-1,2-cyclohexanediol at 180°. Phosphonic esterification takes place only in the presence of a b-COOH function and appears as a necessary condition for the crosslinking ability, provided that enough carboxylic esterification can take place. Cyclic five-membered anhydrides are proposed as reaction intermediates but only carboxylic anhydrides could be evidenced. .
