Title: The thermal copolymerization of aspartic acid and glutamic acid
Abstract: Thermal condensation of aspartic acid and glutamic acid yields copolymeric products. In typical reactions for periods of 6 hr. or less, mean molecular weights range from 5000 to 25,000. The products are largely polyimides which are convertible by mildly alkaline treatment to materials which are fully linear peptides. The ratios of aspartic acid to glutamic acid in the total composition and in the N-terminal composition have been studied over a wide range of conditions. The proportion of glutamic acid in the N-terminal position in the product obtained, however, is much larger than the proportion in the total composition. This fact suggests in principle that the order of residues in a thermal copolyamino acid would be nonrandom.
