摘要 |
<p>Amidoamines of the following formula are described: <CHEM> where R is independently hydrogen or lower alkyl of 1 to 4 carbon atoms; R' is an alkyl group if k is 1, or an alkylene group if k is greater than 1; where R' has 2 to 18 carbon atoms; R'' is independently lower alkylene of 1 to 4 carbon atoms; R''' is independently straight or branched lower alkylene of 2 to 6 carbon atoms; x is independently 1 to 200; y is independently 1 to 300; z is independently 0 to 200; p is independently 2 to 11; and k is from 1 to 8; where the x and z groups may be distributed in blocks or randomly. These compositions may be made by reacting a cyclic lactam with a polyether-polyamine. The polyamidopolyfunctional amines have a relatively low modulus and retain higher use temperatures than current polyetheramide segment block copolymers. The polyamidopolyether amines may be further interconnected through reaction with dicarboxylic acids and esters. <IMAGE></p> |
