AQUEOUS ADHESIVE COMPOSITION WITH A BASE OF BIOSOURCED ALDEHYDE AND POLYPHENOL

摘要

The aqueous adhesive composition comprises an unsaturated elastomer latex and a phenol/aldehyde resin based on an aldehyde of formula (I): in which X comprises N, S or O and R represents —CHO, and based on a polyphenol comprising one or more aromatic nucleus/nuclei. When there is just one aromatic nucleus, the latter bears two or three hydroxyl functional groups in the meta position with respect to each other, the remainder of the aromatic nucleus being unsubstituted. When there are several aromatic nuclei, at least two of them each bear two or three hydroxyl functional groups in the meta position with respect to each other, the two positions ortho to at least one of these hydroxyl functional groups being unsubstituted.
