Abstract: front page image
(EN)A polymer containing carboxylate groups which is formed by polymerization, in the absence of toxic or inflammable solvents, of a water-soluble salt of a compound of the formula: (FORMULA) in which R represents C15H31-n, C17H35-n or C11H23 in which n is 0, 2, 4 or 6, and X represents H or OH, with an aldehyde, preferably formaldehyde in the form of paraformaldehyde. Preferred starting materials are derived from both natural and Technical cashew nut shell liquid (CNSL) including 4-pentadecyl-salicyclic acid and 5-pentadecylresorcinol-2-carboxylic acid, both new compounds, obtained by subjecting Technical CNSL to carboxylation by the Kolbe reaction. The components may be polymerized in alkaline aqueous medium and used to bond particulate and/or fibrous materials, e.g. particle board of wood chips
(FR)Un polymere contenant des groupes carboxylates est forme par polymerisation, en l'absence de solvants toxiques ou inflammables, d'un sel soluble dans l'eau d'un compose de formule: (FORMULE) ou R represente C1H31-n, C17H35-n ou C11H23 dans lesquels n vaut 0, 2, 4 ou 6, et X represente H ou O H, avec un aldehyde, de preference un formaldehyde sous forme de paraformaldehyde. Des materiaux de depart preferes sont derives du liquide de coquille de noix d'acajou a la fois naturelle et technique (CNSL) comprenant de l'acide 4-tentadecyle-salicyclique et l'acide 5-tentadecylresorcinol-2-carboxylique, ceux-ci etant tous deux des composes nouveaux, obtenus en soumettant du CNSL technique a une carboxylation par la reaction de Kolbe. Les composants peuvent etre polymerises dans un milieu aqueux alcalin et utilises pour lier des materiaux particulaires et/ou fibreux par exemple des planches de copeaux de bois agglomeres.
