The present document describes a polyamide hot-melt resin having a chemical structure consisting of dimerized fatty acids and diamines, loaded with an active ingredient. The dimerized fatty acids may have 12 to 24 carbons and the diamines may have 2 to 14 carbons. The amine residual functional groups and acid residual functional groups within the polyamide hot-melt resin may have a [NH2]/[COOH] molar ratio below 5, and the active ingredient may be incorporated in quantities of between about 0.01 and about 55% by weight of weight of the resin. The present document also describes items molded from the polyamide hot-melt resins, and processes of preparing the polyamide hot-melt resins.
A polyamide hot-melt resin having a chemical structure consisting of dimerized fatty acids and diamines, said polyamide hot-melt resin being loaded with an active ingredient,
A molded item made from a plurality of polyamide hot-melt resin granules synthesized from dimerized fatty acids having 12 to 24 carbons and diamines having 2 to 14 carbons, said resins granules being loaded with active ingredient, wherein said polyamide hot-melt resin granules have amine residual functional groups and acid residual functional groups in a [NH2]/[COOH] molar ratio below 5 and in a quantity of said active ingredient between 0.01 and 55% by weight compared to the total weight of the molded item, said item having been molded by injection-molding, blow-molding, extrusion, hot-pressing or coating.
