Abstract

DC60 (15/01/42) This invention provides a block-building polyester amide with an amide or ester structure containing the following monomers: - aliphatic dialcohol or cycloaliphatic alcohol and/or - aliphatic dicarboxylic acid, including its associated esters and/or - aromatic dicarboxylic acid, including its associated esters and/or - hydroxycarboxylic acid and lactone and/or - aminoalcohol and/or - cyclic lactam and/or - w-aminocarboxylic acid and/or - a mixture (1:1 salt) of dicarboxylic acid and diamine. The polyester amide is obtained by polycondensation of ester block terminated with hydroxyl acid or ester and of amide block terminated with amino acid. Or terminated by ester. The ester content of the polyesteramide is between 20 and 80 w%, and the amide content is between 80 and 20 w%. This invention yields a block polyesteramide with either an amide or ester structure containing the following monomers: - aliphatic dialcohol or cycloaliphatic alcohol and/or - aliphatic dicarboxylic acid, including its associated esters and/or - aromatic dicarboxylic acid, including its associated esters and/or - hydroxycarboxylic acid and lactone and/or - aminoalcohol and/or - cyclic lactan and/or - w-amid carboxylic acid and/or - a mixture (1:1 salt) of dicarboxylic acid and diamine. This polyesteramide is obtained by polycondensation of esters. Polyesteramide blocks are terminated by hydroxyl acids or esters, and amide blocks are terminated by amino acids or esters. The ester content of polyesteramide is between 20 and 80 kg%, and the amide content is 80-20 kg%.

Claims (4)

1. Polyesteramides have an amide or ester structure and contain the following monomers: - aliphatic dialcohol or cycloaliphatic alcohol and/or - aliphatic dicarboxylic acid, including its associated esters and/or - aromatic dicarboxylic acid, including its associated esters and/or - hydroxycarboxylic acid and lactone and/or - aminoalcohol and/or - cyclic lactan and/or - w-amid carboxylic acid and/or - a mixture (1:1 salt) of dicarboxylic acid and diamine. This polyesteramide is obtained by polycondensation of ester blocks terminated with hydroxyl acid or ester and of amide blocks terminated with amino acids or esters. The esterification of this polyester... The teramide content is between 20 and 80 kg%, and the amide content is 80-20 kg%. 2. Polyesteramides under claim 1, which have been formed by polycondensation of a mixture of two ester blocks terminated by a hydroxyl acid or ester or more, and a mixture of two amide blocks terminated by an amino acid or ester or more. 3.
