摘要：
Polyamide reaction products comprising: a dicarboxylic acid and a diamine component comprising a mixture of poly(oxytetramethylene) diamines and oligomers of said poly(oxytetramethylene) diamines,said mixture containing from about 85 to about 99.5 wt. % of said poly(oxytetramethylene) diamines and, correspondingly, from about 15 to about 0.5 wt. % of said oligomers,said poly(oxytetramethylene) diamines having the formula: ##STR1## wherein n represents 0 or a positive number having a value of 1 to about 30,said oligomers having the formula: ##STR2## wherein n represents 0 or a positive number having a value of 1 to about 30.
