摘要： Amidamines of the following formula are described: ##STR1## 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 2 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 1 to 200;p is independently 2 to 11; andk is from 1 to 8; where the x and z groups may be distributed in blocks or randomly.These compositions are made by reacting a cyclic lactam with an etheramine. Incorporation of increasing quantities of the polyetherpolyamine did not decrease the crystalline melting point (T.sub.m) of the resulting copolymer. The polyamidopolyfunctional amines (poly(amide-ether-amide) triblock copolymers) 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, esters and the like.

摘要： Disclosed is an alternating block copolymer composition useful for enhancing the crystallization of bisphenol-A polycarbonate which comprises the reaction product of a polyoxyalkylene polyamine and poly(ethylene)terephthalate. Also disclosed is a method of synthesizing the alternating block copolymer and a method of using the block copolymer composition in the crystallization of bisphenol-A polycarbonate.

摘要： Described are carboxyl-terminated polyetheramides of the formula: ##STR1## where R is a moiety from an alcohol or hydroxy compound having a valence of k; R' is independently hydrogen or lower alkyl from 1 to 4 carbon atoms; R" is independently a straight or branched alkylene or aromatic moiety averaging from about 2 to 36 carbon atoms; x averages from about 2 to 100; z averages from about 20 to about 250; k averages from about 1 to 3; m is 0 or 1; and p is independently 5 to 11. Because the carboxyl-terminated polyetheramides are all carboxyl-terminated, they do not gel. They are expected to have good impact strength as well as differing solubilities depending on the polyetheramine incorporated.
摘要翻译：描述了下式的羧基封端的聚醚酰胺：其中R是具有k价的醇或羟基化合物的部分; R'独立地为氢或1至4个碳原子的低级烷基; R“独立地是平均约2至36个碳原子的直链或支链亚烷基或芳族部分; x平均为2〜100左右; z平均从约20到约250; k平均从1到3; m为0或1; 并且p独立地为5至11.由于羧基封端的聚醚酰胺全部是羧基封端的，它们不凝胶。预期它们具有良好的冲击强度以及不同的溶解度，这取决于所掺入的聚醚胺。
