| abstract | polyamide containing 1,4-butylene diamine monomeric units A process for producing a polyamide containing 1,4-butylene diamine monomeric units, an aliphatic dicarboxylic acid of 6 to 12 carbon atoms and a fatty acid-based dicarboxylic acid and / or a diamine derived therefrom, characterized in that the process comprises the steps of: a) obtaining an aqueous salt mixture containing 1,4-butylene diamine, aliphatic dicarboxylic acid having 6 to 12 carbon atoms and the fatty acid and / or diamine-based dicarboxylic acid derived therefrom, the mixture containing less than 50% by weight of water and distilling the mixture to less than 15% by weight of water at a pressure of less than 16%. barg (1,600 kpag) while maintaining the mixture at a temperature sufficiently high to maintain its liquid, b) initiating polymerization of the mixture obtained in step a) by increasing the temperature to at least 180 ° C until at least 80% of the reactive groups have been converted, c) optionally and additionally providing 1,4-butylene diamine, an aliphatic dicarboxylic acid having 6 to 12 carbon atoms and a fatty acid and / or dicarboxylic acid based dicarboxylic acid. diamine from the reaction mixture. The invention further relates to the obtained polyamide, a composition comprising polyamide and the shaped articles made of the composition. |
