Summary: ATPB may serve as a new type of propellant binder through click chemistry reaction between alkynyl and azide group, with significant implications for design. The study reveals that both terminal C equivalent to C and middle C=C bonds of ATPB can react with azide groups, with the reactivity of the C equivalent to C bond being significantly higher than that of the C=C bonds. Additionally, the use of copper (I) catalyst weakens the reaction between azide group and the C=C bonds of HTPB.

Summary: This study demonstrates the significant role of thiyl radicals produced by thiol oxidation in driving the spontaneous thiol-ene polymerization in the absence of solvents, heating, and intentional radical formation. Factors influencing reactivity, kinetics, solvation of thiols, and nature of initiating radicals were studied through various techniques, showing that the polarization of S-H bond drives thiol air oxidation. Thiols with electron-withdrawing substituents and hydrogen-bonded thiol-solvent (or thiol-alkene) complexes promote self-initiation by increasing S-H bond polarization.
