vious data reported in the literature. [24][25][26][27][28] In this respect, however, further studies are in progress. Experimental SectionIntrinsic viscosities were measured at 30°. Since the yields of all the poly(amide amines) listed were always practically quantitative, elemental analysis determinations were considered to be irrelevant. This polymerization being a polyaddition, in fact, the values obtained for the products could not be expected to be different from that of the monomeric mixtures. That under the conditions used no other reaction but polyaddition takes place between amines and compounds bearing activated double bonds has been previously demonstrated.29 Polymer Gr To a cooled (5°) solution of 1.94 g of 1,4-bisacryloyl-piperazine30 in 10 ml of ethanol, 9 ml of aqueous 1M ethanolamine and 1 ml of ethanolic 1 M «-dodecylamine were added under nitrogen. The mixture was thoroughly shaken and then kept in the dark at room temperature under a nitrogen atmosphere for 4 days. The solvents were then evaporated under reduced pressure and the product was dried at 45°under vacuum (0.1 mm). The yield was practically quan-
