the use of proton NMR was described by the Authors as a valid method to assess the occurrence of the transamidation reactions between MXD6 and PA6I-6T polyamides and to determine the block length and randomness degree around the isophthalic units.
These include the formation of anionic polyacrylamide through hydrolysis, (17) the synthesis of sulfomethylated derivatives from the reaction of polyacrylamide with formaldehyde and sodium bisulfate, (18) the formation of aminomethylated polyacrylamide from the reaction of polyacrylamide with formaldehyde and dimethylamine (Mannich reaction), (19) and the generation of various derivatives by transamidation reactions including hydroxamated polyacrylamides used as a flocculant in the Bayer process.
Transfer of GPI to proteins is mediated by GPI-transamidase, which recognizes the GPI-attachment signal sequence and replaces it with the GPI-precursor by a transamidation reaction (Fig.
It has been reported that cross-linking by amidation between carbonyl and [epsilon]-amino groups or by transamidation between such groups with the elimination of ammonia occurs upon severe heat treatment in protein molecules (Feeney, 1975).
Estradiol-regulated transamidation of keratins by vaginal epithelial cell transglutaminase.
Asn] in a distinct tRNA-dependent transamidation reaction (6).
The distribution of the monodisperse amide segments did not broaden upon melt polymerization, suggesting that hardly any transamidation reactions took place (8).
It has been reported that cross-linking by amidation between carbonyl and a-amino groups or by transamidation between such groups with the elimination of ammonia occurs upon severe heat treatment in protein molecules (Feeney, 1975).
This could be ascribed to a diluent effect of the amorphous component, characteristic of miscible crystalline-amorphous blends (14) and/or to transamidation reactions between the blend components during the melt-mixing process (15).
Since amic acid formation is an equilibrium reaction, transamidation can occur when two PAAs or two precursors with very similar structure are combined in solution.
This was attributed to transamidation reactions occurring between the blend components, leading to the formation of in-situ block copolymers.
