Abstract

DC60 (20/08/42) is a statistically synthesized aliphatic-aromatic polyesteramide whose main monomers are the following: - aliphatic dialolons such as ethylene glycol, diethylene glycol, 1,4-butanediol, 1,3-propanediol, 1,6-hexanediol, or cycloaliphatic diols such as cyclohexane dimethanol, and/or - aliphatic dicarboxylic acids such as oxalic acid, succinic acid, adipic acid, and other acids, which may also exist in the form of esters (methyl, ethyl, etc.) of each of these acids. And/or aromatic dicarboxylic acids such as tyrephthalic acid, isophthalic acid, phthalic acid, and other acids, which may also be in the form of esters (methyl, ethyl, etc.) of each of these acids; and/or hydroxycarboxylic acids and lactones such as caprolactone and other substances; and/or amino alcohols such as ethanolamine, propanolamine, etc.; and/or cyclic lactams such as epsilonprolactam or lauryllactam, etc.; and/or omega-aminocarboxylic acids such as aminoproic acid, etc.; and/or mixtures (1:1 salts) of dicarboxylic acids such as adipic acid, succinic acid, tyrephthalic acid, etc., and diamines such as hexamethylenediamine. Diaminobutane, etc., containing aromatic dicarboxylic acid (as a percentage of the acid) not exceeding 70 mole percent. Aliphatic-aromatic polyesteramide synthesized using statistical principles with the following main monomer components (chemical formulas) containing aromatic dicarboxylic acid (as a percentage of the acid) not exceeding 70 mole percent.

Claims (4)

1. Aliphatic-aromatic polyesteramides synthesized using statistical principles, with the following main monomers: aliphatic dialols, cycloaliphatic diols, and/or aliphatic dicarboxylic acids which may also exist as esters of each of these acids, and/or aromatic dicarboxylic acids which may also exist as esters of each of these acids, and/or hydroxyl carboxylic acids, lacdotone, and/or aminoalols, and/or cyclic lactams, and/or omegacarboxylic acids, and/or mixtures (1:1 salts) of dicarboxylic acids and diamines, with the aromatic dicarboxylic acid content (relative to acid content) not exceeding 70 mol%. 2.
