    Abstract: An absorbent binder desiccant composition is provided which is capable of spontaneous crosslinking after application to a substrate, at a temperature of about 120~C or less. The absorbent binder desiccant composition includes a monoethylenically unsaturated polymer, such as carboxylic acid, sulphonic acid, or phosphoric acid, or salts thereof, or a quaternary ammonium salt, and an acrylate or methacrylate ester that contains an alkoxysilane functionality, or a monomer capable of co-polymerization with a compound containing a trialkoxy silane functional group and subsequent reaction with water to form a silanol group, and a desiccant component. The absorbent binder desiccant composition is particularly suitable for use in manufacturing a wide variety of humidity control articles.

    Abstract: The invention relates to α-ethoxysilane modified polymers of the average general formula (I): in which R is a mono- to tetravalent polymer radical, not more than a third of the radicals R1, R2, and R3 present in the polymer of the formula (I), independently of one another, are alkyl radicals having 1 to 4 carbon atoms, at least a quarter of the radicals R1, R2, and R3 present in the polymer of the formula (I), independently of one another, are ethoxy radicals, any remaining radicals R1, R2, and R3, independently of one another, are methoxy radicals, and in which n is 1 to 4. The invention further relates to a process for preparing the polymers of the formula (I), and also to their use in adhesives, sealants, and coating materials.
