A polymer consisting mainly of structural units represented by the general formula (1), wherein the total molar amount of terminal aldehyde groups and acetal groups is 0.6 mol% or smaller based on the total molar amount of the structural units represented by the general formula (1). -[-(-CHR1-)n-CX1R2- CX2R3-]- (1) (In the formula, n is an integer of 2 to 10; X1 and X2 each represents -H, -OH, or a functional group capable of being converted into -OH, provided that at least one of X1 and X2 is hydroxy or a functional group capable of being converted into hydroxy; and R1, R2, and R3 each represents -H or C1-5 alkyl, aryl, aralkyl, or heteroaryl and the two or more R1's may be different.)

L'invention concerne un polymère composé principalement d'unités structurelles de formule générale (1), dans laquelle la quantité molaire totale des groupes aldéhyde terminaux et des groupes acétal est inférieure ou égale à 0,6 % en moles, en fonction de la quantité molaire totale des unités structurelles de formule générale (1). -[-(-CHR¿1?-)¿n?-CX¿1?R¿2?-CX¿2?R¿3?-]- (1), où n est un nombre entier de 2 à 10, X¿1? et X¿2? représentent chacun H, -OH ou un groupe fonctionnel apte à être converti en OH, dans la mesure où au moins X¿1? ou X¿2? signifie hydroxy ou un groupe fonctionnel apte à être converti en hydroxy, R¿1?, R¿2? et R¿3? désignent chacun H ou alkyle C¿1-5?, aryle, aralkyle ou hétéroaryle, les deux R¿1? ou plus pouvant être différents.
