    Notes: Acrylates, such as ethyl acrylate, add with amino alcohol to form N-(hydroxyalkyl) β-alanine ester and room-temperature polycondensation follows, forming polyamide in the presence of a basic catalysts, such as alkali metal alkoxide. The reaction medium has an influence on the course of the polycondensation; that is, N-(hydroxyalkyl) polyamide is formed in methanol solution and polyamide ether in other solvents, such as tetrahydrofuran. These two courses of the room-temperature polycondensation have been studied, and the reaction mechanism is discussed in this paper.

    Room-temperature polycondensation of β-amino acid derivatives VI. Synthesis of various N-(hydroxyethyl) nylonsFor Part V, see Sanui and Ogata.1 (1969)

    Notes: Various N-(hydroxyethyl)amino acid esters having a methyl substituent or phenyl group between amine and ester groups have been synthesized and their polycondensation behavior was investigated. These substituted amino acid esters gave amorphous polyamides which were soluble in alcohol. A model reaction between N-(hydroxyethyl)-amine and carboxylic acid ester was carried out in order to elucidate the role of hydroxyethyl group on the polycondensation. It was found that the amidation reaction took place rapidly at room temperature when the alkyl group of the carboxylic acid was small. N-(Hydroxyethyl) polyamides were obtained from N,N′-(bishydroxyethyl)-dicamines and dicarboxylic acid esters. The reaction mechanism of the room-temperature polycondensation reaction is discussed.
