Patent

CA 2560776

The present invention is directed to carboxylic acid and ester moieties that are attached to a carbon chain that is between 2 and 24 carbons in length wherein, the chain contains at least one dioxanone ring system, said dioxanone being formed from two adjacent carbons in the chain and/or at least one carbon in the chain is substituted with a pendant dioxanone ring system. In preferred embodiments, the carbon chain is a fatty acid residue. The carbons of said chain can be optionally substituted, saturated or unsaturated. When two or more said ester moieties are present, the invention is directed to a polyester such as a triglyceride, that contains multiple carbon chains wherein each chain is independently derivatized such that the triglyceride contains at least one dioxanone ring system, said dioxanone being formed from two adjacent carbons in at least one of said chains. The present invention is also directed to a method of preparing a dioxanone containing composition of fatty acid derivative. The present invention is also directed to coating formulations and polymers that utilize a dioxanone containing composition or fatty acid derivative, and methods of making such coatings and polymers.

Un acide carboxylique et des fragments d'ester sont fixés à une chaîne de carbone comprenant entre 2 et 24 carbones en longueur, la chaîne contenant au moins un système cyclique de dioxanone, ledit dioxanone étant formé de deux carbones adjacents dans la chaîne et/ou au moins un carbone dans la chaîne est substitué par un système cyclique de diaxonone pendant. Dans des modes de réalisation préférés, la chaîne de carbone est un résidu d'acide gras. Les carbones de la chaîne peuvent être éventuellement substitués, saturés ou insaturés. Lorsque deux fragments d'ester au moins sont présents, on prévoit un polyester, notamment un triglycéride, contenant de multiples chaînes de carbone, chaque chaîne étant indépendamment dérivée de manière que le triglycéride contienne au moins un système cyclique de diaxonone, le diaxonone étant formé à partir de deux carbones adjacents dans au moins une des chaînes. Un procédé de préparation du diaxonone contenant une composition ou un dérivé d'acide gras. Des formulations de revêtement et des polymères utilisant un diaxonone contenant une composant ou un dérivé d'acide gras, ainsi que des procédés de fabrication de tels revêtements et polymères.
