Patent

CA 2394764

The invention relates to polyesters that are appropriate as softeners and that are obtainable by reacting aliphatic dicarboxylic acids, neopentylglycol, at least one further diol and a nonanol mixture. Said nonanol mixture substantially consists of 1-nonanol, monomethyl octanols, dimethyl heptanols and monoethyl heptanols. The invention further relates to the nonanol mixture and to the use of the inventive polyesters as softeners.

L'invention concerne des polyesters pouvant être utilisés comme plastifiant, que l'on obtient par réaction d'acides dicarboxyliques aliphatiques, de néopentylglycol, d'au moins un autre diol et d'un mélange contenant du nonanol, ce mélange étant constitué principalement de 1-nonanol, de monométhyloctanols, de diméthylheptanols et de monoéthylheptanols. L'invention concerne également ledit mélange contenant du nonanol et l'utilisation de ces polyesters comme plastifiant.
